Answer:
360
Step-by-step explanation:
1. Set up your equation!
[tex]\frac{35}{100}[/tex] = [tex]\frac{126}{x}[/tex]
2. Cross multiply to solve!
100 times 126 = 12600
35 times x = 36x
3. Continue!
12600=35x
4. Divide the coefficient on both sides to get the variable by itself
[tex]\frac{12600}{35}[/tex]=x (the 35 cancels out)
12600 divided by 35 = 360
And there’s your answer! 360

Answer:
1) f=650 2) a=16 3) d=91
Step-by-step explanation:
1) To make f=...
We can multiply both sides by 26
f=26×25
f=650
2) To make a=...
We can divide both sides by 5
a=80÷5
a=16
3) To make d=...
We can times both sides by 7
d=13×7
d=91

Solve this system of equations.
Answer:
(8,0)
Step-by-step explanation:
y= 0.50x - 4
y= -0.25x + 2
I changed it to make it:
0.25x + y = 2
-0.50x + y = -4
--
We subtract the y's and every equation to cancel out the y.
0.25x - (-0.50x) = 0.75x
2-(-4)=6
0.75x = 6
x = 8.
Plug the x into either equation. We'll do the first eqn.
0.25(8)+y=2
2 = y = 2
y = 0.
(8,0).
Answer:
x = 8, y = 0
Step-by-step explanation:
Given system of equations:
[tex]\begin{cases}y=\dfrac{1}{2}x-4&\\y=-\dfrac{1}{4}x+2\end{cases}[/tex]
First, substitute the first equation into the second:
[tex]\implies \dfrac{1}{2}x-4=-\dfrac{1}{4}x+2[/tex]
SOLVE FOR X.
Step 1: Multiply both sides by [tex]4[/tex] and simplify.
[tex]\\\implies 4\left(\dfrac{1}{2}x\right)-4(4)&=4\left(-\dfrac{1}{4}x\right)+2(4)\\\\\implies \dfrac{4}{2}x-16=-\dfrac{4}{4}x+8\\\\\implies 2x-16=-x+8[/tex]
Step 2: Add (1)[tex]x[/tex] to both sides.
[tex]\\\implies 2x + x-16=-x+x+8\\\\\implies 3x-16=8[/tex]
Step 3: Add [tex]16[/tex] to both sides.
[tex]\\\implies3x-16+16=8+16\\\\\implies 3x=24[/tex]
Step 4: Divide both sides by [tex]3[/tex].
[tex]\\\implies \dfrac{3x}{3}=\dfrac{24}{3}\\\\\implies \boxed{x=8}[/tex]
SOLVE FOR Y.
Step 1: Substitute [tex]8[/tex] as the value of [tex]x[/tex] in any of the given equations.
[tex]\\\implies y=\dfrac{1}{2}(8)-4[/tex]
Step 2: Simplify.
[tex]\\\implies y=4-4\\\\\implies \boxed{y=0}[/tex]
The solution to this system of equations is (8,0).

The student council is asking people to donate money for the new park outside the school. Everyone who makes the suggested donation amount will be given a bracelet.
If everyone donates the suggested amount, and b bracelets are given away, what is the algebraic expression that represents the total amount collected in donations?
Answer:
x(b) or b(x)
Step-by-step explanation:
x for the number of people who suggested.
b for the number of bracelets given.
The bracelets are not needed in this equation because they do not relate the the total amount of donations collected.
let's first introduce some variables:
let p= the number of people
let d= the suggested amount of of donation
equation:
number of people × suggested amount of donation
d×p
What is the effect of multiplying both sides of an inequality by a negative number? Explain and give an example.
Answer: You would swap the ineqaulity
Step-by-step explanation:
Multiplying or dividing both sides by a negative number reverses the inequality. This means < changes to >, and vice versa. For example, given that 5 < 8 we can multiply both sides by 6 to obtain 30 < 48 which is still true.
There are 80 girls and 70 boys in the sixth grade. Of these students, 11 girls and 7 boys are left handed. What percentage of the sixth graders are left handed?
Answer: 12%
Step-by-step explanation:
Total number of people in 6th grade: 70+80 = 150
Total numbers of lefties: 11 + 7 = 18
Percent:
18 ÷ 150 = 0.12
0.12 x 100 = 12
Answer:
12%
Step-by-step explanation:
80+70=150 which is the whole
11+7= 18 which is the part
The equation is
Part= Percent x Whole
18= % x 150 or 18 divided by 150 is
.12 or 12%

Kelvin went skiing with his family. They kept track of how long they each skied without falling. The table lists the longest time that each family member skied without falling.
Person Time Skied
(seconds)
Kelvin 223
Lori 55
Vanessa 265
Devon 172
Celia 112
Arnold 356
Part A
Kelvin wants to know whether he skied without falling more than twice as long as anyone else in his family. His dad tells him that he can check by using the inequality 2f < 223, where f is the time skied in seconds for each person. Plug the values for the time skied by each person into the inequality to find the answer.
Kelvin did not skied without falling more than twice as long as anyone else in his family.
Answer:
He only skied more than Lori.
Step-by-step explanation:
Lori*2: 110
Vanessa*2: 530
Devon*2: 344

The 10-second barrier in the 100-meter dash was first broken in the 1968 Olympics, when the winning time was 9.95 seconds. A gym teacher ran the 100-meter dash in 14.7 seconds. How much faster was the 1968 Olympic time than the gym teacher’s time
HELP
Answer:
4.75 seconds
Step-by-step explanation:
14.7 - 9.95
Answer:
The Olympian completed the 100-meter dash 4.75 seconds faster than the gym teacher. You could also say he was 3.25 meters per second faster.
Step-by-step explanation:
To get 4.75 I just subtracted and found the difference between both of their times.
To find the difference between their speeds, I divided 100 by each time to get each person's distance per second. The olympian's speed was 10.05 meters per second and the gym teacher's speed was 6.80 meters per second. To find the difference between these, I subtracted the same way I did with the time difference.

Isolate for the variable by collecting like terms
Use inverse operations to rearrange an equation
Answer:
x must be 9 (Answer C).
Step-by-step explanation:
The two angles marked in red are "vertical angles," and, as such, they are equal: 5x - 8 = 2x + 19.
Combining like terms results in 3x = 27, and therefore x must be 9 (Answer C).
