This is the equation: 3x-2=5x+15
<span>you combine like terms: 3x-3x-2=5x-3x+15 </span>
<span>the 3x on the left cancles out: -2=2x+15 </span>
<span>subtract 15 on both sides: -2-15=2x+15-15 </span>
<span>the 15 on the right cancles out:--17=2x </span>
<span>divide by 2: -17/2=2x/2 </span>
<span>x equals negative 8.5: x=-8.5</span>

Answer:
The product of 60 and 4000 is 240,000
Step-by-step explanation:
If you are asked to work out the product of two or more numbers, then you need to multiply the numbers together.
Answer:
B.
Step-by-step explanation:
First in order to solve this problem we need to simplify the answer choices.
A. 6×8 + 6×6 = 48+ 36
B. 12×4 + 12×1=48+12
C. 4×44 + 4×3=176+12
D. 8×6 + 8×4 = 48+32
As you can see there is one expression that is equivalent to 48+12. Answer choice B is correct.
Answer:
A: The x-intercept of k(x) is half the x-intercept of h(x)
Step-by-step explanation:
Answer choices B, C, and D are concerned with slopes and y-intercepts. The coefficients of x in the functions are different and are related by a factor of -2, so the lines are not parallel, and one slope is not twice the other. The y-intercepts (constants) in each function are different, so they graphs do not cross the y-axis at the same place.
Hence answer choices B, C, and D can be eliminated.
The x-intercepts are found by setting y=0 and solving for x:
h(x) = 0 = -2x +4 ⇒ x = 4/2 = 2
k(x) = 0 = 4x -4 ⇒ x = 4/4 = 1
The x-intercept of k(x) is half that of h(x). . . . . . . matches choice A
