Answer:
×=-0.8
Step-by-step explanation:
3×2=6
6+9=15
19x+15=0
subtract 15 from both sides
19x=-15
divide both sides by 19
x=-0.789 which rounds up to -0.8
Answer:
Step-by-step explanation:
D = distance
v = speed
t = time
Distance formula says that
You are given
miles
hour
is unknown.
Substitute them into the distance formula:
![\dfrac{3}{4}=v\cdot \dfrac{2}{3}\\ \\3\cdot \dfrac{3}{4}=2v\ [\text{Multiplied by 3}]\\ \\\dfrac{9}{4}=2v\\ \\v=\dfrac{\frac{9}{4}}{2}\ [\text{Divided by 2}]\\ \\v=\dfrac{9}{4}\cdot \dfrac{1}{2}=\dfrac{9}{8}=1\dfrac{1}{8}\ \text{miles per hour}](https://tex.z-dn.net/?f=%5Cdfrac%7B3%7D%7B4%7D%3Dv%5Ccdot%20%5Cdfrac%7B2%7D%7B3%7D%5C%5C%20%5C%5C3%5Ccdot%20%5Cdfrac%7B3%7D%7B4%7D%3D2v%5C%20%5B%5Ctext%7BMultiplied%20by%203%7D%5D%5C%5C%20%5C%5C%5Cdfrac%7B9%7D%7B4%7D%3D2v%5C%5C%20%5C%5Cv%3D%5Cdfrac%7B%5Cfrac%7B9%7D%7B4%7D%7D%7B2%7D%5C%20%5B%5Ctext%7BDivided%20by%202%7D%5D%5C%5C%20%5C%5Cv%3D%5Cdfrac%7B9%7D%7B4%7D%5Ccdot%20%5Cdfrac%7B1%7D%7B2%7D%3D%5Cdfrac%7B9%7D%7B8%7D%3D1%5Cdfrac%7B1%7D%7B8%7D%5C%20%5Ctext%7Bmiles%20per%20hour%7D)
