question: find the value of t
Answer:
t = 5
Step-by-step explanation:
since those 2 angles make up 180 degrees turn it into an equation
20t + 5 + 15t = 180
combine like terms 20t + 15t = 35t
the equation is now 35t + 5 = 180
subtract 5 from both sides, 5 - 5=0, 180 - 5 = 175
35t = 175
now divide each side by 35, 35t/35 = t, 175/35= 5
t = 5
hope this helps :)
Answer:
5
Step-by-step explanation:
Line (which has the the equation)= 180
So,
15t + 20t + 5 = 180
35t + 5 = 180
35t = 180 - 5
35t = 175
t = 175/35
t = 5
Find the area of the parallelogram. Round to the nearest hundredth if necessary.
Answer:
1424.81 square meters
Step-by-step explanation:
20.21 m * 70.5m = 1424.805 square meters
So then you round it to the nearest hundredth so then..
1424.81 square meters
Step-by-step explanation:
A of a parallelogram = Base ×height
= 20.21×70.5= 1424.805m
nearest hundreth = 1424.81 m
Marion is driving between two towns that are close together. If she drives 1/5 the distance of the trip in 15 minutes, what is her rate per hour?
Answer: 75 minutes per hour.
Step-by-step explanation:
From the question, we are informed that Marion is driving between two towns that are close together and that she drives 1/5 the distance of the trip in 15 minutes.
The rate per hour will then be:
= 15 ÷ 1/5
= 15 × 5
= 75 minutes
The rate per hour will then be 75 minutes per hour.

i'm really confused on this, anything will help
Answer:
I think its 1200 not sure though
Answer:
1,200
Step-by-step explanation:
first you would divide 480 copies by 4 minutes to see how many copies per minute (120) Then you would take 120 copies per minute and multiply it by the 10 and you would get 1200 copies per 10 minutes! lmk if that helps:)

Answer:
TUA=123
Step-by-step explanation:
so first we find <TUS in terms of x
so 180-11x-2
178-11x
so now we can use the sum of a triangle's angles which is always 180 to find the angles in triangle TUS
178-11x+5x+10+58=180
178-6x=112
take 178 from both sides
-6x=-66
x=11
so we can do 11x11+2=TUA
TUA=123
Jaden is saving money to buy a bike that costs $290. He has saved $140 so far. He plans on saving $25 each week. Write and solve an equation to determine in how many weeks (identify the question) Jaden will have enough money to buy the bike.
What does the variable in question 4a represent?
Answer:
25w+140=290
He will have enough money in 6 weeks
w represents the amount of weeks
Step-by-step explanation:
25w+140=290
$25 every week + the original $140 = the total needed $290
Answer:
140 + 25w = 290
w = 6
Step-by-step explanation:
Goal: $290
Currently have $140
Saving $25 each week (variable)
Start with your given amounts :
(base) 140 + 25w (variable solving for) = 290 (goal you want equation to equal)
w stands for the amount of weeks for the goal to be reached
Solve:
140 + 25w = 290
subtract 140
25w = 150
divide 25
w=6
Double check (optional but suggested)
140 + 25 (6) = 290
140 + 150 = 290
290 = 290
correct
12 = 6y - 36
Solve for y
Answer:
y=8
Step-by-step explanation:
add 36 to 12. then divide 48 (the result) by 6 to get 8
Answer:
Y=8
Step-by-step explanation:
12 = 6 x y - 36
12=6 x 8 - 36
12 = (6x8) - 36
12 = 48 - 36
Y= 8

A collection of dimes and nickels is worth 3.30. if there are 42 coins in total how many of each kind of coin are there?
Answer:1 nickels =$0.05
1 dime= $0.1
Step-by-step explanation:
1 nickels =$0.05
1 dime= $0.1
let the number of nickels be x and that of dimes be y.
total number of coins is given by:
x+y=42
hence:
y=42-x.......i
total amount of cash will be:
0.05x+0.1y=3.30.........ii
substituting i in ii we get:
0.05x+0.1(42-x)=3.30
0.05x+4.2-0.1x=3.3
-0.05x=-0.9
x=-0.9/(-0.05)
x=18
hence the the number nickels is x=18, the number of dimes will be y=42-x=42-18=24
NEED ANSWERS ASAP!!! - How do you find the value of x??
Answer: Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.

What is the solution to the equation? 12 = |X| - 3 X= -36 or 36 X= -9 or 9 X = -4 or 4 X = -15 or 15
Answer:
x = -15 or 15
Step-by-step explanation:
We can simplify |x| - 3 = 15 to |x| = 15 because we can add 3 on both sides due to -3 being outside of the absolute value bars. Next, we can say that x is either 15 or -15 because of the absolute value (|15| is equal to 15 and |-15| is also equal to 15).

Zahn takes a summer job selling ice cream bars at the pool. He receives a fixed salary and then additionally a commission for each ice cream bar he sells. The table shows Max's total earnings, y, in dollars, from selling x ice cream bars:

Select the equation that best represents the relationship between x and y. (5 points)
a
y = x + 34
b
y = 4x + 30
c
y = 4x + 42
d
y = x + 42
Answer: B
If you look at the table, you notice that he earns 30 without selling ice cream bars. This is his fixed salary.
When he sells one ice cream bar, he earns 34, which means he gets 4 dollars for each bar he sells.
The equation that best represents the relationship between x and y is b) y = 4x + 30, because 4 dollars × number of ice cream bars + fixed salary equals his total earnings.

c=-1
c=5
c=7
Given:
A quadratic equation is
[tex]-6=x^2+4x-1[/tex]
To find:
The standard form of the given equation and find the value of c.
Solution:
The standard form of a quadratic equation is
[tex]ax^2+bx+c=0[/tex] ...(i)
We have,
[tex]-6=x^2+4x-1[/tex]
It can be rewritten as
[tex]0=x^2+4x-1+6[/tex]
[tex]0=x^2+4x+5[/tex]
[tex]x^2+4x+5=0[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]c=5[/tex]
Therefore, the value of c is equal to 5 and the correct option is C.
