4a + 3 = 15
- 3
4a = 12
÷ 4
a = 3
I hope this helps!
Not sure if I quite understand your question. But ill assume that you're asking if 1 times 7 is positive. Or if 1x7 is positive.
1 times 7 equals 7 so it is a positive integer.
1x7 can be positive or negative depending on what x equals. If x is a negative number then the whole expression is negative. If x is postive the expression is positive.
Answer:
She messed up the equation, A= B x h, she changed it midway, and also, you need to add the one half to make the equation valid
Step-by-step explanation:
A=1/2 x b xh
17.5 = 1/2 x 5 x h
35=5h (multiply both sides by 2 to get rid of one half)
35/5 = 5h/5
7=h
The height of the triangle is 7 units

Answer:
Midpoint coordinates are 
Step-by-step explanation:
The Coordinates of R = (-8,3)
The Coordinates of S = (9, -7)
Let M be the mid point of M and its coordinates by (x,y)
Now, by mid point formula,
⇒
So, the midpoint coordinates are
32,000 x 3
96,000
Answer: 96,000
