Answer:
x = -0.35
Step-by-step explanation:
tep 1 - Multiply 64 and 0.5x. The answer ends up being 32x
Step 2 - You need to get all of the variables on one side and the regular numbers on the other side. To do that, you need to subtract 2.5x from each side so you are left with the equation -10.5 = 29.5x
Step 3 - The final step is to isolate the variable. To do this, you divide each side by 29.5 meaning that x = -0.35
For this case we have that by definition, the point-slope equation of a line is given by:
Where:
It is a point through which the line passes
m: It is the slope of the line
According to the data we have to:
Substituting:
Finally, the equation of the line is:
ANswer:
Number 19
price :$16
pay :10%
ask:each monthly payment
answer:
pay =10%×$160=$16
each monthly payment
={$160-$16}÷6
144÷6
$24
number 20
weight earth:150 pounds
ratio :5:7
weight neptune :7/5×150=210 pounds
.75 Rounded to the nearest thousandth would be 0.750
Mercury: 87 24/25
Venus 224 7/10
Mars 686 49/50
All we need to do is to convert fractions so they have a denominator of 10, 100, 1000 etc.
87 24/25 = 87 96/100
224 7/10 stays the same
686 49/50 = 686 98/100
Now we can easily convert them into decimals:
Mercury: 87.96
Venus: 224.7
<span>Mars: 686.98</span>
