Answer:

(-3, 1).

Step-by-step explanation:

2x + 7y = 1 -------------(A)

x + 5y = 2 Multiply this by -2:

-2x - 10y = -4 Add this equation to equation (A):

0 - 3y = -3

3y = 3

y = 1.

Substitute this in equation (A):

2x + 7(1) = 1

2x = -6

x = -3.

Check if these 2 values are correct in the second equation:

-3 + 5(1) = 2

2 = 2.

Marta said 50 + one-half m = 120 is an equation, while Maribel argued that it is an expression. Determine who is correct and exp

In-s [12.5K]

Answer:

Marta

Step-by-step explanation:

We are given that

$50+\frac{1}{2}m=120$

We have to find who is correct and explain.

We know that

Equation: It is mathematical sentence that combines numbers and variables which shows the equality of two expressions.

Example:

$x+y=3$

Expression: It is mathematical phrase that combines numbers and variables

using mathematical operators.It can be evaluated but not solved.

Example:

$x+y$

By definitions

$50+\frac{1}{2}m=120$

It is in equation form.

Therefore, Marta is correct.
