Help for number 10 please

tamaranim1 [39]

Start with

$4(3^3-8) \div 2$

Exponents have the highest priority, so we evaluate 3 cubed first:

$4(27-8) \div 2$

Next, we have to solve parenthesis first: we have 27-8 = 19, so the expression becomes

$4 \times 19 \div 2$

Multiplications and divisions have the same priority, so we perform them as they appear: $4 \times 19 = 76$ , so the expression becomes

$76 \div 2 = 38$

The age of a father is two less than seven times the age of his son in two years the sum of their ages will be 57 if the son's p

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:

$f = 7s -2$

$f + s =53$
