Answer:
D
Step-by-step explanation:
Firstly, we need to get the value of x 1-7 < 3x
-6 < 3x
-2 < x
or x > -2
So we need a number line that has the unshaded circle placed at 2 ( since the inequality sign is single) and it faces the right (arrow face right)
<u>Answer:</u>
45
<u>Step-by-step explanation:</u>
We are given an equation <em>x - y = 30 </em>which we are to solve for x when the value of y is 15.
To solve this linear equation for x, we just need to substitute the given value of y into the equation to get the value of x.
x - y = 30
x - 15 = 30
x = 30 + 15
x = 45
Therefore, the value of x is 45 when y = 30.
Unfortunately this value is not in the given options but 45 is the correct answer.
Answer:
B, 9/4 = 9 * 1/4
Step-by-step explanation: 
. Just multiply the numerator by the numerator and denominator by the denominator.
Answer:
C. P = 1.6w + 8.5
Step-by-step explanation:
In y= mx + b,
8.5 is (b) because it is the starting weight. The baby's weight gain would be represented by (m), because it changes every week.
Your answer should be the third and forth options
