Answer:

This alot but ill help you with 2 of them to learn em

Step-by-step explanation:

1) 2x^2 +5 =167

Subtract the 5 from both sides to get the equation 2x² = 162

Then divide the 2 from both sides to get x² = 81, Then square root from both sides to get x= 9

6) 2(2y +4)²=72

Divide 2 from both sides to get (2y+4)²=36

Then square root that to get 2y+4 = 6

subtract 4 from both sides to get 2y =2

Then divide both sides from 2. Y=2

ASHA 777 [7]

Answer:

f = 7s -2

f  + s =53

Step-by-step explanation:

Given

Let

f = Father's age

s = Son's age

We'll solve this question, while reading through the instructions

From the first statement;

f is 2 less than 7 times s.

This means

f = 7s -2

In two years time, the father will be f +2 and the son will be s + 2

So, their sum is:

(f+2) + (s + 2) = 57

f + 2 + s + 2 =57

Collect like terns

f  + s =57-2-2

f  + s =53

So, the equations are:

f = 7s -2

f  + s =53

If the value of 3/4 divided by x Is the whole number which number is the value of x?
gregori [183]

A whole number is a number that has no fractional representation.

Let's test all the options for the value of x.

When dividing a fraction by another fraction, the divisor will be in its reciprocal form.

1. 3/4  × 2/3

= 6/12 = 1/2

1/2 isn't a whole number.

2. 3/4 × 2/1

= 6/4 = 3/2

3/2 isn't a whole number.

3. 3/4 × 6/1

= 18/4 = 9/2

9/2 isn't a whole number.

4. 3/4 × 8/1

= 24/4 = 6

6 is a whole number.

Hence the answer is 1/8.

Hope it helps. :)
