Answer:
-3x-12
Step-by-step explanation:
This is a problem of distribution.
Distribute means to multiply the variable outside the perenthesis to what's inside the perenthesis.
What you are going to do is distribute the -3 to the x and 4
-3 times x is -3x
-3 times 4 is -12
Make sure the signs are correct and the new expression is -3x-12
Study the steps used to solve the equation

Step 5: c = 24
Answer:
c = 24
Step-by-step explanation:
The given equation is :
[tex]\dfrac{c}{2}-5=7[/tex]
Adding both sides by 5 both sides,
[tex]\dfrac{c}{2}-5+5=7+5\\\\\dfrac{c}{2}=12[/tex]
Cross multiplying both sides,
[tex]c=2\times 12[/tex]
c = 24
So, the value of c is 24.

1. Yearly membership with the online music club costs $48. Members pay $0.99 per song to download music. Nonmembers may download songs for $1.29 each.
Answer:
160 musics
Step-by-step explanation:
let the total amount/charges be y
let the number of musics be x
For members total
y=48+0.99x-------1
For non-members total
y=1.29x-------------2
we are expected to solve for the number of music where members and non members get to pay the same amount
equating 1 and 2 we have
48+0.99x=1.29x
48=1.29x-0.99x
48= 0.3x
x=48/0.3
x=160 musics

Vivian is at a fair in Coachella Valley, California. Much of the valley lies below sea level. Vivian has brought along an altimeter to measure her elevation at different places in the valley. Vivian's first ride was on the Ferris wheel. When she sat on the wheel at its lowest point, her altimeter read -9.6 feet. When she reached the top of the wheel, her altimeter read 12.3 feet.
Answer:
21.9 feet
Step-by-step explanation:
The question is incomplete. Here is the complete question.
Vivian is at a fair in Coachella Valley, California. Much of the valley lies below sea level. Vivian has brought along an altimeter to measure her elevation at different places in the valley. Vivian’s first ride was on the Ferris wheel. When she sat on the wheel at its lowest point, her altimeter read -9.6 feet. When she reached the top of the wheel, her altimeter read 12.3 feet.
Is the change in Vivian's elevation from the bottom of the Ferris wheel to the top a positive number or a negative number? Why?
Given parameters
Altimeter of vivian at its lowest point = -9.6 feet
Altimeter of vivian at the top of the wheel = 12.3feet
Note that the sea level is at 0 feet.
change in Vivian's elevation from the bottom of the Ferris wheel to the top is expressed as:
= (12.3-0)+(0-(-9.6))
= 12.3+(0+9.6)
= 12.3+9.6
= 21.9 feet
From the gotten value, it can be seen that the change in Vivian's elevation from the bottom of the Ferris wheel to the top is a positive value.
The value is positive because vivian keeps moving to the top of the wheel (above the sea level). The values above the sea level is always positive.
Answer:Hide Sample Answer
The change in Vivian's elevation is a positive number because her elevation increased as she moved from the bottom of the Ferris wheel to the top.
Step-by-step explanation:Hide Sample Answer
The change in Vivian's elevation is a positive number because her elevation increased as she moved from the bottom of the Ferris wheel to the top.

Carlos biked StartFraction 139 over 8 EndFraction miles on Saturday and StartFraction 135 over 7 EndFraction miles on Sunday. On which day did he ride further and by how much? Carlos rode further on Saturday by 1 and StartFraction 51 over 56 EndFraction miles. Carlos rode further on Saturday by 3 and StartFraction 5 over 56 EndFraction miles. Carlos rode further on Sunday by 3 and StartFraction 51 over 56 EndFraction miles. Carlos rode further on Sunday by 1 and StartFraction 51 over 56 EndFraction miles.
Answer:
Carlos rode further on Sunday by [tex]1\frac{51}{56} miles[/tex] miles.
Step-by-step explanation:
Carlos covered distance on Saturday [tex]=\frac{139}{8}[/tex]
He covered distance on Sunday = [tex]\frac{135}{7}[/tex]
Equivalent fractions:
[tex]\frac{139}{8} \times \frac{7}{7}=\frac{973}{56}\\ \frac{135}{7} \times \frac{8}{8}=\frac{1080}{56}[/tex]
So,[tex]\frac{1080}{56}>\frac{973}{56}\\ \frac{135}{7}>\frac{139}{8}[/tex]
So, He covered more distance on Sunday
Difference between distances =[tex]\frac{1080}{56}-\frac{973}{56}=\frac{107}{56}=1\frac{51}{56}[/tex]
So, Carlos rode further on Sunday by [tex]1\frac{51}{56} miles[/tex] miles.

A line is given by the equation y=x+2. Determine which of the following points belong to this line: M(0, 2),N(1, 3), A(−1, 1), B(−4.7, −2.7), C(−2 1 2 , 1 2 ).
Answer:
A(-1, 1)
Step-by-step explanation:
Answer:
M,N,A,B
Step-by-step explanation:
all the points above satisfy the given eqn
eg, A(-1,1)
y=x+2,x=-1
y=-1+2
y=1 but C doesn't satisfy the eqn (-2 1/2,1/2)
y= -2 1/2 +2
y= -1/2
