Answer:
x = 10
Step-by-step explanation:
You can compare parts of each expression to see that x in the left-side expression is replaced by 10 in the right-side expression.
x = 10
__
If you'd rather, you can work your way down to the same conclusion by undoing the operations that have been done to x.
(6x -1)° = (6(10) -1)° . . . . . . given
6x -1 = 6(10) -1 . . . . . . . . . divide both sides by °
6x = 6(10) . . . . . . . . . . . . add 1 to both sides
x = 10 . . . . . . . . . . . . . . . . divide both sides by 6

FIND M∠R (GIVING BRAINLIEST, 25 PTS)
Answer:
76Step-by-step explanation:
to understand thisyou need to know about:trianglesequationPEMDASgiven:[tex]M\angle T=2x+2[/tex][tex]M\angle R=3x+1[/tex]tips and formulas:this is an isosceles triangle since two sides are equal therefore [tex]\angle T=\angle S[/tex]a triangle contains 180°let's solve:according to the question
2x+2+2x+2+3x+1=180
solve:
collect like terms:7x+5=180substract 5 from both sides:=>7x+5-5=180-5=>7x=175divide both sides by 7: =>7x/7=175/7x=25given:
M∠R=3x+1
substitute the value of x
3×25+1
75+1
76
Answer:
M∠R=76°
Step-by-step explanation:
First, I realized that ∠S was equal to ∠T, meaning ∠S=2x+2. I then added all 3 angles together and set them equal to 180, seeing the angles of a triangle must add up to 180 (2x+2+2x+2+3x+1=7x+5=180)
After that, I subtracted 5 from 180 and then divided by 7 to get x=25. I then solved the equation 3x+1 by plugging 25 in for x and ended up with 76 as my final answer.

Answer: The length of the hypotenuse (c) is 5
Step-by-step explanation:
Use the Pythagorean Theorem
a² + b² = c²
a & b are the legs (b is the base)
c = hypotenuse
a = 4
b = 3
a² + b² = c²
4² + 3² = c²
16 + 9 = c²
25 = c²
√c² = √25
c = 5

12. Three friends went to an ice cream parlor for ice cream. They each paid $3.51 for their ice
cream, including an 8% sales tax.
What was the total cost of all three bowls of ice cream before tax was added?
$
Answer:
total cost - $3.23 per icecream cone no tax // cost is $9.69 all 3 ice cream cones no tax // solve by multiplying .08 by $3.51. you get .28 // subtract that from $3.51 to solve

What number represents the same amount of 2 hundreds, 14 tens, and 3 ones.
Answer:
i think the answer would be 343?
Step-by-step explanation:
find the length of the third side of the right triangle!!!!
Answer:
8
Step-by-step explanation:
There are two ways to solve this!
1. Use the Pythagorean Theorem
a^2 + b^2 = c^2
6^2 + b^2 = 10^2
100 - 36 = b^2
64 = b^2
8 = b
2. Shortcut using 3-4-5 triangles
A 3-4-5 triangle has to do with the ratios of each side.
In this case, it's 6-8-10, as each number is multiplied by two with the same 3-4-5 ratio. This is a good shortcut for these types of problems and will be handy on tests like the SAT as well! :)

pls help
Answer:
8/25
Step-by-step explanation:
there are 8 numbers from 1 - 25 that are divisible by 3 because 25/3 = 8.3333..
Written out these would be:
3,6,9,12,15,18,21, and 24
so you ahve 8 out of a total of 25
5h – 4 > 6 and 7h + 11 < 32
Answer:
iihi
Step-by-step explanation:
Answer:
h > 2
-------------------------
h < 3
Step-by-step explanation:
5h – 4 > 6
add 4 both sides
5h > 10
divide 5 both sides
h > 2
-------------------------
7h + 11 < 32
subtract 11 both sides
7h < 21
divide 7 both sides
h < 3

Find the value of x
O A.3
O B. 11
O c. 7
OD. 5
Answer:
Step-by-step explanation:
7x+13 = 48
7x = 35
x = 5
Answer:
D. 5
Step-by-step explanation:
The angle should equal 48 degrees as it is congruent to the other angle labeled as 48 degrees.
So, we get the equation 7x + 13 = 48
Subtract 13 from both sides.
7x + 13 - 13 = 7x
48 - 13 = 35
We get 7x = 35
Divide by 7 on both sides.
7x / 7 = x
35 / 7 = 5
We get x = 5.

the perimeter of a rectangle is 30 cm. The height is 5 cm . what is the area of that rectangle.
Answer:
Pretty sure its 50
Step-by-step explanation:
if the height is 5, that would be multiplied by 2 because there are two identical sides. From the product, 10, you would need to get to 30, so you add 20. that means the other two identical sides are 10cm. 10x5 (length x width) is equal to 50.
Answer:
[tex]30 = 2 \times l + 2 \times b \\ 30 = 2 \times 5 + 2 \times b \\ 30 = 10 + 2b \\ 30 - 10 = 2b \\ 20 = 2b \\ = 20 \div 2 = 10 \\ area = l \times b \\ 5 \times 10 = 50cm {}^{2} [/tex]

Hank's car travels 600 feet in 20 seconds. Andy's motorcycle travels 300 feet in 12 seconds. Which is faster, the car or the motorcycle? Explain your reasoning.
Answer:
the car travels faster
Step-by-step explanation:
Since the motorcycle has traveled 300 feet, and the car has traveled 600 feet, we will divide 600 by 2
600 divided by 2 = 300
Hank would have traveled 300 feet in 10 seconds
Andy traveled 300 feet at 12 seconds
Therefore Hanks car travels faster
Answer:
The car travels faster
Step-by-step explanation:
600 ft per 20 secs
How many feet in one sec?
600/20 = 30
Hank's car = 30 feet per second
300 feet in 12 sec
How many feet in one sec?
300/12 = 25
Andy's motorcycle = 25 feet per second
A concert venue has 20 seats in the first row and an 5 additional seats in each successive row. If there are 35 rows of seats then how many people can attend a sold-out show? 3,675 190 2,100
Answer:
3,675 people
Step-by-step explanation:
First row, a = 20
Common difference, d = 5
number of terms, n = 35
Sn = n/2 {2a + (n - 1)d}
= 35/2 {2*20 + (35 - 1)5}
= 35/2 {40 + ( 34)5}
= 17.5(40 + 170)
= 17.5(210)
= 3,675 people
The answer is actually 3675.

Can someone please give me a simple explanation on exponential functions? I need to write a one page essay over what it is
Answer:
The exponential function is one of the most important functions in mathematics (though it would have to admit that the linear function ranks even higher in importance). To form an exponential function, we let the independent variable be the exponent. A simple example is the function

Help sir! Thank you, Mr Thompson
Problem 1
To find the y intercept, plug in x = 0 and simplify
f(x) = (x-2)(x+4)
f(0) = (0-2)(0+4)
f(0) = (-2)*(4)
f(0) = -8
We have x = 0 pair up with y = -8
The y intercept is (0,-8)
Answer: Choice D
========================================
Problem 2
(x-2)(x+4) is the same as x^2+2x-8 after using the FOIL rule. The distributive property is an alternate option.
The leading coefficient of x^2+2x-8 is 1. Since this leading coefficient is positive, it tells us that the parabola opens upward.
Answer: C) Parabola opens upward
========================================
Problem 3
Answers:
A = h(x)B = f(x)C = g(x)Explanation:
Note that 1-x^2 is the same as -x^2+1 and this has a negative leading coefficient. So the parabola opens downward. That must mean curve C matches with function g(x).
Both f(x) and h(x) have the same leading term of x^2. However, the constant terms are different. Because f(x) has a smaller constant (-4 is smaller than 4) this makes curve B to be f(x), while curve A is h(x). The larger the constant is, the further shifted up the curve will be.
