To estimate the sum you must add the estimate of 703 and 620.
700 + 600 (estimated) would be = 1,300
On solving the linear system, for the value of y = 15, the value of x is 200. The correct option is D.
<h3>What is the linear system?</h3>
It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Given
The linear equation is shown below.

The equation can be written as

For y = 15, the value of x will be.

The value of x is 200.
Thus, option D is correct.

Answer:
Step-by-step explanation:
To multiply 4×5⅜, the mixed number can be broken down into a whole number and a fraction. In this case, that whole number would be 5 and the fraction would be three-eighths. Each of these parts are then multiplied by 4 and the products are added together.
4×5⅜ = 4×(5+⅜)
= 4×5 + 4×⅜
= 20 + 3/2
= 20 + 1½
= 21½
Answer:
Step-by-step explanation:
A positive correlation is a relationship between two variables that move in tandem—that is, in the same direction. A positive correlation exists when one variable decreases as the other variable decreases, or one variable increases while the other increases.
