Step-by-step explanation:
5x +7 y=-17
4x – 3y = -5
Substitute.
Answer:
(x,y) = (-2, -1)
Step-by-step explanation:
We start off by substituting the value of "x".
5x+7y=-17
x=-[tex]\frac{5}{4} + \frac{3}{4}y[/tex]
We then solve 5[tex]5(-\frac{5}{4}+\frac{3}{4}y ) +7y= -17[/tex]
y=-1 *Substitute the value of "y"
x= -[tex]-\frac{5}{4}+\frac{3}{4}x(-1)[/tex]
x=-2
[tex]\left \{ {{-17=-17} \atop {-5=-5}} \right.[/tex] This works.
Convert 0.33333...in to a fraction
Step-by-step explanation:
Let x = 0.3333333...
Then 10x = 3.3333333....

Pablo rented a truck for one day. There was a base fee of $10.50, and there was an additional charge of 6 cents for each mile driven. The total cost, C (in
dollars), for driving x miles is given by the following.
C =0.06x+10.50
What is the total rental cost if Pablo drove 40 miles?
Answer:
$12.90
Step-by-step explanation:
For 40 miles for 0.06 cents with each mile, it would be $2.40 for the extra added with the base fee makes it $12.90.

If (52)p = 512, what is the value of p?
Answer:
p=9.846153846
Step-by-step explanation:
you distribute the p to the 52, then divide 512 by 52 to get p by it's self.
AKA: 512/52p -------> p=9.846153846
A city employee paints curbs in parking lots and replaces road signs. It takes 0.5 hour to paint a parking lot curb and 2.5 hours to replace a road sign
Question is incomplete. Here is the complete question.
A city employee paints curbs iin parking lots and replaces road signs. It takes 0.5 hour to paint a parking lot curb and 2.5 hours to replace a road sign. The function below can be used to find c, the number of parking lot curbs the employee paints when he replaces r road signs in a 40-hour workweek.
[tex]c=\frac{40-2.5r}{0.5}[/tex]
If the employee painted 20 curbs in one week, how many road signs did he replace that week?
a) 20 b) 30 c) 0 d) 12
Answer: d) 12
Step-by-step explanation: In one week, the employee painted 20 curbs.
c is the number of curbs painted in one week, so: c = 20
[tex]20=\frac{40-2.5r}{0.5}[/tex]
[tex]40-2.5r=20*0.5[/tex]
[tex]-2.5r=10-40[/tex]
[tex]-2.5r=-30[/tex]
[tex]r=\frac{-30}{-2.5}[/tex]
r = 12
In one week, the employee replaced 12 road signs.
Given the points A(-2,-1) and B(-6,5), find the value of the y-coordinate of point C which is 23 from point A to point B.
Given:
Points A(-2,-1) and B(-6,5).
Point C which is 2/3 from point A to point B.
To find:
The y-coordinate of point C.
Solution:
Let the coordinates of point C are (a,b).
Point C which is 2/3 from point A to point B.
AC:AB = 2:3
AC:CB = AC:(AB-AC) = 2:(3-2) = 2:1
Section formula: If a point divides the line segment in m:n, then then
[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]
Point C divides AB in 2:1, soby section formula
[tex]C=\left(\dfrac{2(-6)+1(-2)}{2+1},\dfrac{2(5)+1(-1)}{2+1}\right)[/tex]
[tex]C=\left(\dfrac{-12-2}{3},\dfrac{10-1}{3}\right)[/tex]
[tex]C=\left(\dfrac{-14}{3},\dfrac{9}{3}\right)[/tex]
[tex]C=\left(\dfrac{-14}{3},3\right)[/tex]
Therefore, the y-coordinated of point C is 3.
Using the distributive property and combining like terms, simplify the expression.

Which number is equivalent to the improper fraction 35/4
Step-by-step explanation:
If you want to make the improper fraction into a mixed fraction/decimal;
35/4 = 32/4 + 3/4 = 8 3/4 = 8.75.
The number equivalent to the improper fraction 35/4 is 8 3/4.
We have,
To convert the improper fraction 35/4 into a mixed number, divide the numerator (35) by the denominator (4):
35 ÷ 4 = 8 remainder 3
The quotient, 8, represents the whole number part, and the remainder, 3, represents the numerator of the fractional part.
So, the equivalent mixed number is:
8(3/4)
Therefore,
The number equivalent to the improper fraction 35/4 is 8 3/4.
