Answer:
y = -1
Step-by-step explanation:
Step 1: Write equation
2(y + 2) - y = 3(y - 1) + 9
Step 2: Solve for y
Distribute: 2y + 4 - y = 3y - 3 + 9Combine like terms: y + 4 = 3y + 6Subtract y on both sides: 4 = 2y + 6Subtract 6 on both sides: -2 = 2yDivide both sides by 2: -1 = yRewrite: y = -1Step 3: Check
Plug in y to verify it's a solution.
2(-1 + 2) - (-1) = 3(-1 - 1) + 9
2(1) + 1 = 3(-2) + 9
2 + 1 = -6 + 9
3 = 3

Sharon has a cake she wants to share with her friends. If she gave 2/5 to Sam and 1/5 to mary. How much does she have left for herself?
Answer:
2/5 of the cake
Step-by-step explanation:
First, find how much she gave away:
2/5 + 1/5
= 3/5
Then, to find how much she has left, subtract 3/5 from 1
1 - 3/5
= 2/5
So, she has 2/5 of the cake left for herself

HELP ASAP NOW NOW NOW NOW!!! Suppose three riders rode a total of 182 miles.
If they used a total of 13 horses, and rode each horse the same number of miles, how many miles did they ride before replacing each horse?
They rode _____ miles before replacing each horse.
Answer:
14 miles
Step-by-step explanation:
Assuming each horse was only ridden once
then a total of 13 horses were ridden for a total of 182 miles
182 miles / 13 horses = 14 miles horse
Of course, if each horse was ridden more than once before being replaced the distance between replacements could be reduced.
Note that the fact that there were 3 riders is irrelevant.
find the rate of interest when principal rs 6400 SIMPLE INTEREST RS 768 and time 2 years
Answer:
rate of interest is 6 percent per annum.
Step-by-step explanation:
Formula for simple interest is given
SI = p*r*t/100
where
SI is simple interest
p is principal
r is the rate of interest
t is the time
_______________________________
Given
p = 6400
SI = 768
t = 2 years
r we have to find
lest sue the above formula and plug the given value in it
768 = 6400*r*2/100
=> 768 = 128r
=> r = 768/128 = 6
Thus, r = 6%
thus, rate of interest is 6 percent per annum.
what are the steps for solving -4+2x=5-(x-3)+3x
Answer:
I Couldn't find a variable to solve for. This equation is invalid, the left and right sides are not equal, therefore there is no solution.
Step-by-step explanation:
Simplify
-4 + 2x = 5 + -1(x + -3) + 3x
Reorder your terms
-4 + 2x = 5 + -1(-3 + x) + 3x
-4 + 2x = 5 + (-3 * -1 + x * -1) + 3x
-4 + 2x = 5 + (3 + -1x) + 3x
Combine your like terms 5 + 3 = 8
-4 + 2x = 8 + -1x + 3x
Combineyour like terms -1x + 3x = 2x
-4 + 2x = 8 + 2x
Add -2x to each side of your equation.
-4 + 2x + -2x = 8 + 2x + -2x
Combine your like terms: 2x + -2x = 0
-4 + 0 = 8 + 2x + -2x
-4 = 8 + 2x + -2x
Combine your like terms: 2x + -2x = 0
-4 = 8 + 0
-4 = 8
Solving
-4 = 8

i don't understand how to solve this 136 - (-128.6) =
Answer:
264.6
Step-by-step explanation:
Answer:
264.6
Step-by-step explanation:
ok first of all if you are subtracting a negative the it becomes a positive
136 - (-128.6)
136 + 128.6
this is what goes on in my head you don't have to do it this way but i do
100 + 100 = 200
30 + 20 = 50
6 + 8.6 = 14.6
200 + 50 + 14.6 = 264.6

ninth grade algebra.i am solving for x
Answer: x = 1
Step-by-step explanation:
So you need to get x completely alone, so take c out of it by subtracting c
-3x = -3 -2c
x = 1 +2/3c
so you would plug that in to solve for C
So you know what x is (or the substitute for it right now)
-3(1 + 2/3c) + 2c = -3
multiply or add
-3 - 2c + 2c = -3
c is 0 when you combine
-3x + 0 = -3
-3x = -3
x = 1

The graph below shows how much money you have in savings each week. Use
this graph to answer questions (a – g).
a. According to the graph how much money did you start with in your savings?
b. How much money will you have after 5 weeks of saving?
Answer:
Step-by-step explanation:
a). Since starting point of the line is (0, 50),
Therefore, I started with the saving of $50.
b). Since endpoint of the segment is (5, 175),
Money with me after 5 weeks will be $175.
c). Let the equation of the line given in the graph is,
y - y' = m(x - x')
Where (x', y') is a point lying on the graph.
And 'm' is the slope of the line.
Slope of the line = [tex]\frac{175-50}{5-0}[/tex]
m = [tex]\frac{125}{5}[/tex]
m = 25
Since, the line passes through (0, 50),
y - 50 = 25(x - 0)
y = 25x + 50
y = 25x + 50
For x = 6,
y = 25×6 + 50 = 200
For x = 7,
y = 25×7 + 50 = 225
For x = 8,
y = 25×8 + 50 =250
d). For x = 10 weeks,
y = 25×10 + 50 = $300
e). For x = 15 weeks
y = 25×15 + 50 = $425
f). For x = 50 weeks,
y = 25×50 + 50 = $1300
g). Equation of the line is,
y = 25x + 50

what is m pqr (3x-5) (x+1)
The value of measure ∠PQR is,
⇒ ∠PQR = 133°
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
In the given figure,
⇒ ∠PQR = (3x - 5)°
⇒ ∠ RQS = (x + 1)°
Now, By the figure we can conclude,
⇒ ∠PQR + ∠ RQS = 180°
Substitute the given values, we get;
⇒ (3x - 5) + (x + 1) = 180
⇒ 4x - 4 = 180
⇒ 4x = 180 + 4
⇒ 4x = 184
⇒ x = 184/4
⇒ x = 46
Thus, The value of measure ∠PQR is,
⇒ ∠PQR = (3x - 5)°
⇒ ∠PQR = (3 × 46 - 5)°
⇒ ∠PQR = (138 - 5)°
⇒ ∠PQR = 133°

A drink is mixed in the ratio
lemonade : orange : cranberry = 6 : 3 : ?
If the fraction for cranberry juice is 3/12, what would be the missing number in the ratio?
Answer:
3
Step-by-step explanation:
Drink mix ratio:
Lemonade : Orange : Cranberry
6 : 3 : C
Fraction of Cranberry juice = [tex]\frac{3}{12}[/tex]
Sum of the ratio = 6 + 3 + C = 9 + C
Fraction of Cranberry;
[tex]\frac{C}{9 + C}[/tex] = [tex]\frac{3}{12}[/tex]
3(9 + C) = 12C
27 + 3C = 12C
27 = 12C - 3C
9C = 27
C = 3
The missing number will be 3
