Answer:

Well for A, move all terms that don't contain the valiable 'y' to the right side and solve.

Y = 9 − x/2

Or

Y = 9 − \frac{x}{2}

For B, it's really similar to A, just isolate the variable 'h' by dividing each side by factors that don't contain the variable 'h', you get the answer,

H = 2a/b

Or

H = \frac{2a}{b}

For C, it's exactly the same with B. Isolate the variable 'X' by dividing each side by factors that don't contain the variable 'X', the answer you have is,

X = y/4 - 3/4

Or

X = \frac{y}{4} − \frac{3}{4}

Answer:

Step-by-step explanation:

a. To solve for "y" you want to isolate the variable. What this means is you want to keep "y" on its own. To do this first we will subtract 2x from the equation making 4y = 36 - 2x. Next, we will get rid of 4 to do this divide 4 from both sides. y = (36 - 2x)/4

*I have to go in a bit so sry for no explenation*

b. h = 2a/b

c. x = 1/4y + -3/4

√70 is between which two numbers on the number line?
Leto [7]

Answer:

C) 8 and 9

Step-by-step explanation:

We know that 70 is between two perfect squares.

The square numbers 64 and 81 can help us solve this question.

64<70<81

We take square root to get:

\sqrt{64}  \:  <  \:  \sqrt{70}  <  \sqrt{81}

We simplify this to get:

8 \:  <  \:  \sqrt{70}  \:  <  \: 9

Therefore √70 is between 8 and 9.

The correct option is C.

Find the value of y.<br><br> 5<br> 8<br> 4<br> 2<br><br> 50 Pts!
Vinvika [58]

Answer and Explanation:

Since this is a 30-60-90 triangle, you can use the ratio of side lengths specific to this type of triangle:

x = 4√(2)

y = 2(4) = 8

because where 4 = T,

x = T√2    and     y = 2T

so again:

x = 4\sqrt{2}\\y = 8
