Malik asked his teacher if there was a way to check his answer after writing equivalent expressions. what should be his teacher’s response? -choose a number to substitute for the variable. find the value of each expression. if the values are even, the expressions are equivalent. -substitute a number for the variable. if the simplified expressions have the same value, the expressions are equivalent. -multiply each expression by the same number. if the expressions are equal, the expressions are equivalent. -add a number to each expression. if the simplified expressions are equal, the expressions are equivalent.

Substitute a number for the variable. If the simplified expressions have the same value, the expressions are equivalent.

Step-by-step explanation:

Given that Mallik asked his teacher if there was a way to check his answer after writing equivalent expressions

To check answer in algebraic equations or equivalent expressions the best way is to substitute the answer for the variable in the expression and check whether the values are even.

Hence correct choice is option 2.

Substitute a number for the variable. If the simplified expressions have the same value, the expressions are equivalent.

marco saved more.   he saved $35 more.

step-by-step explanation:

1+2+3+4+5+6+7+8+9+10 = 55

2*10 = 20

55-20 = 35

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
