Answer:
Equality Sign
Step-by-step explanation:
A child may be at educational risk if he is unable to use the equality sign as it is the basis for comparison of numbers.
Once a child can determine if two numbers are the same, we can then proceed to introduce comparisons of numbers. That is, either it is more than a stated number or less.
For example,
If number of apples=6, a child who understands this will know if 5 apples are less or more as appropriate.
The x is a placeholder for a number. Think of x like a box and inside the box will go a number. In this case, -4 will replace x
7 - 2x = 7 - 2(-4) = 7 + 8 = 15
<h3>Answer: 15</h3>
Answer
C. x=2
Step-by-step explanation:
This is due to 2(2) = 4
then 3^4=81
81*4=324
Answer:
2x - 5y = -13
Step-by-step explanation:
The equation of a straight line can be written as
(y - y1) = m(x - x1), where the coordinates are (x1,y1) and gradient is m.
Hence by applying this formula, we get:
y - 1 = 2/5 (x + 4)
5y - 5 = 2(x + 4) (Multiply both sides by 5)
5y - 5 = 2x + 8 (Expand the Right Hand Side)
5y - 2x = 13 (Bring the variables to one side)
2x - 5y = -13 (Multiply both sides by -1)
Hence Answer is <u>2x - 5y = -13</u>
