How to solve 4y-2/5y 4/5 = -3

One operator is missing. I will assume it is a + and that the equation is: 4y -2/5y +4/5 = -3

Solution step by step

1) Sum -4/5 to both sides

4y - 2/5y + 4/5 - 4/5 = -3 -4/5

2) Sum alike terms

18/5 y = -19/5

3) Multiply both sides by 5

18 y = -19

4) Divide both sides by 18

y = -19/18

<span>1. 5564÷91
I know that 9 * 6 = 56
5564 rounds to 5600
91 rounds to 9
Since 56/9 = 6, then 5600/90 is the same as 560/9 = 60
The estimate is 60

2. </span><span>5391÷25
5391 sounds to 5400
25 is 1/4 of 100.
That means when you divide by 25, you can divide by 100 and multiply by 4.
5400/100 = 54
54 * 4 = 216
Estimate: 216

3. </span><span>explain how to estimate 498÷12
48/12 = 4
498 is little more than 480, so 498/12 is little more than 40

4. </span><span>which is the closest estimate for 2130÷ 33
A.7 B.17 C.70 D.700

2130/33
Round off the numerator and denominator to
2100/30
Reduce the fraction
210/3
Since I know that 21/3 = 7, then 210/3 = 70
Estimate: 70

Rewrite the function to make it easy to graph using transformation of its parent function. Describe the graph. y = squ(25x - 25)
Mariana [72]
Parent function is y=√x
result is
-4+√(25(x-1))

-4 was added to whole function so translated 4 units down
it every x was multipied by 25  so horizontally stretched bya factor of 25
then, minus 1 from every x to move to right

so the blanks are
strech 25, 1 to the right, 4 down

What is the value of x?<br><br><br><br> Enter your answer in the box.
Lapatulllka [165]

We can see that

there are six sides

so, n=6

so, firstly we will find total angle

total angle =(n-2)*180

total angle =(6-2)*180

total angle =720

so, sum of all angles must be 720

so, we get

x+120+100+128+133+112=720

now, we can solve for x

x+593=720

x=127.............Answer

Solve only for x: 3(x-y)=8(x+z)
pshichka [43]

Answer:

x=-8z/5 - 3y/5

Step-by-step explanation:

distributive prop

3x-3y=8x+8z

isolate x by moving 8x to the left, and -3y to the right

-5x=3y+8z

divide by -5 on both sides.

x=-8z/5 - 3y/5
