The length of a rectangle is 7 less than the width. If the
perimeter is 50. What is the length and width? Write
an equation for the situation and solve.
Answer:
Step-by-step explanation:
Let width = w
Length = w - 7
Perimeter = 2*(length + width)
2*(w-7 + w) = 50
2* (2w - 7) = 50
2*2w - 7*2 = 50
4w - 14 = 50
Add 14 to both the sides
4w = 50+ 14
4w = 64
Divide the entire equation by 4
w = 64/4
w = 16 units
Length = 16 - 7 = 9 units

A family has two cars. The first car has a fuel efficiency of 35 miles per gallon of gas and the second has a fuel efficiency of 25 miles per gallon of gas. During
one particular week, the two cars went a combined total of 1925 miles, for a total gas consumption of 65 gallons. How many gallons were consumed by each of
the two cars that week?
Let x = gallons consumed by car 1
Let y = gallons consumed by car 2
We set up our equations:
35x+40y = 1850 eq1
x+y = 50 eq2
Substituting eq 2 into eq 1,
35x+40(50-x) = 1850
35x+2000-40x = 1850
-5x+2000 = 1850
-5x = -150
x = 30
Substitute value of x into eq 2.
x+y = 50
30+y = 50
y = 20
Car 1 consumes 30 gallons of gas.
Car 2 consumes 20 gallons of gas.

−38d−57≥−19d+76 solve for d
Answer:
Step-by-step explanation:
- 38d - 57 ≥ - 19d + 76
- 38d + 38d - 57 - 76 ≥ - 19d + 38d + 76 - 76
-133 ≥ 19d
-133/19 ≥ 19/19d
-7 ≥ d
Answer:
[tex]d\leq -7[/tex]
Step-by-step explanation:
Move all terms containing [tex]d[/tex] to the left side of the inequality.
Add [tex]-19d[/tex] to both sides of the inequality.
[tex]-38d-57+19d\geq 76[/tex]
Add [tex]-38[/tex] and [tex]19d.[/tex]
Move all terms not containing [tex]d[/tex] to the right side of the inequality.
Add [tex]57[/tex] to both sides of the inequality.
[tex]-19d\geq 76+57[/tex]
Add [tex]76[/tex] and [tex]57.[/tex]
[tex]-19d\geq 133[/tex]
Divide each term by [tex]-19[/tex] and simplify.
Divide each term in [tex]-19d\geq 133[/tex] by [tex]-19[/tex]. When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign.
[tex]\frac{-19d}{-19} \leq \frac{133}{-19}[/tex]
Cancel the common factor
[tex]\leq \frac{133}{-19}[/tex]
Divide [tex]133[/tex] by [tex]-19.[/tex]
[tex]d\leq -7[/tex]
The result can be shown in multiple forms.
Inequality Form:
[tex]d\leq -7[/tex]

Step-by-step explanation:
Find the expression that is equivalent to (2v-3)(5v-1)
1. 7v²+13v+3
2. 7v²-13v-3
3. 10v²+17v-3
4. 10v²-17v+3
Answer:
[tex]10v^2-17v+3[/tex]
Step-by-step explanation:
To find the equivalent of this expression we have to use the FOIL method
So you multiply the first terms [tex]2v*5v[/tex]
Then multiply the outer terms [tex]2v*-1[/tex]
Then multiply the inner terms [tex]-3*5v[/tex]
Then multiply the last terms [tex]-3*-1[/tex]
find the slip of every line that is parallel to the graph of the equation x-8y=-1
Answer:
1/8
Step-by-step explanation:
x-8y=-1
First, put the equation in slope intercept form ( y= mx+b where m is the slope and b is the y intercept)
-8y = -x-1
y = 1/8x +1/8
The slope is 1/8 and the y intercept is 1/8
The slope for parallel lines is the same for all parallel lines
1/8

How do i get x in this? 6x - 24 = 6x
Answer:
-24 does not equal 0, so therefore there's no solution.
Step-by-step explanation:
In order to get x by its self, you first have to subtract 6x on both sides to get -24 = 0. Next divide 12 on both sides to get -2 = x.

Find the inequality represented by the graph in the picture below
Answer:
[tex]y \geq2x - 5[/tex]
Step-by-step explanation:
First off, we can tell that the line has a positive slope because it's going upwards to the right. To find the slope of the line exactly, we will start at the first given point and count the units until we get to the next point.
(Remember that slope is written as rise/run.)
So the slope is 2/1 or just 2.
Next, we can tell that the y-intercept is -5, because that's where the line crosses the y-axis.
Additionally, since the line is solid, the inequality sign will either be the "greater than or equal to" sign, or the "lesser than or equal to" sign. In order to tell which one to use, we will look at the shaded area. Since the shaded area is above the line, y will be "greater than or equal to" the line.
So to put it together: The line written in slope-intercept form, is
[tex]y \geq2x - 5[/tex]
Hope this helps you :)

Answer:
Radius = 7cm , Circumference = 43.96cm
Step-by-step explanation:
To find the radius, you divide the diameter by 2.
14 / 2 = 7cm
To find the circumference, you multiply 兀 ( 3.14 ) with the diameter
兀d = 兀 x 14 = 43.96cm
can anyone heelp me plz plz
Answer:
c
Step-by-step explanation:
i think it's 1
Rachel is blowing up a balloon so that the diameter increases at the rate of 10 cm/sec. At what rate must she blow air into the balloon when the diameter measures 4 cm
Using implicit differentiation, it is found that she must blow air at a rate of 251.33 cm³/sec.
A balloon has a spherical format.The volume of a sphere of radius r is given by:
[tex]V = \frac{4\pi r^3}{3}[/tex]
The radius is half the diameter, hence:
[tex]r = \frac{d}{2}[/tex]
[tex]r^3 = \frac{d^3}{8}[/tex]
[tex]V = \frac{4\pi d^3}{24} = \frac{\pi d^3}{6}[/tex]
Applying implicit differentiation, the rate of change of the volume is:
[tex]\frac{dV}{dt} = \frac{d^2 \pi}{2}\frac{dd}{dt}[/tex]
The diameter increases at the rate of 10 cm/sec, hence [tex]\frac{dd}{dt} = 10[/tex].It is of 4 cm, hence [tex]d = 4[/tex]The rate that she must blow air is:
[tex]\frac{dV}{dt} = \frac{d^2 \pi}{2}\frac{dd}{dt}[/tex]
[tex]\frac{dV}{dt} = \frac{4^2 \pi}{2}(10)[/tex]
[tex]\frac{dV}{dt} = 251.33[/tex]
She must blow air at a rate of 251.33 cm³/sec.

Answer to question: 5:12 5/12
Using the diagram and information below to create and solve an equation m<2 =(y+10)° and m<4=(3y-24)° what is m <2
Step-by-step explanation:
m∠2 = m∠4
y + 10 = 3y - 24
y - 3y = -24 - 10
-2y = -34
y = -34/-2
y = 17
m∠2 = y + 10
m∠2 = 17 + 10
m∠2 = 27°
