Answer:
Step-by-step explanation:
[tex]equation: \frac{x}{140} = \frac{30}{100} \\reduced: 100x = 4200\\ solved: \frac{100x}{100} = \frac{4200}{100} \\x = 42[/tex]
An equation is formed of two equal expressions. The equation that shows the relationship 30% of 140 is x is x=0.30×140.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given that 30% of 140 is equal to x. Therefore, we can write,
[tex]\text{30\% of 140} = x\\\\\dfrac{30}{100} \times 140 = x\\\\x = 0.30 \times 140\\\\x=42[/tex]
Hence, the equation that shows the relationship 30% of 140 is x is x=0.30×140.

Factor f(x) into linear factors given that k is a zero of f(x).
f(x) = 4x3 + 23x² – 34x +7; k= 1
f(x) = (Factor completely.)
Step-by-step explanation:
step 1. if k is a zero then (x - 1) is a factor of 4x^3 + 23x^2 - 34x + 7.
step 2. we "can" use long division but synthetic division is easier!
step 3. 1 4 23 -34 7
4. 4. 27. -7.
4 27. -7. 0 (must get 0)
step 4. so the factors are (x - 1)(4x^2 + 27x - 7).
step 5. please note if you multiply these factors together you will get the original polynomial!

Answer:
102
Step-by-step explanation:
x = 180 - (4x - 2) - 78
x = 180 - 4x + 2 -78
5x = 180 + 2 - 78
5x = 104
x = [tex]20\frac{4}{5}[/tex].
So, angle UTW is 4 * [tex]20\frac{4}{5}[/tex] - 2 + [tex]20\frac{4}{5}[/tex] = 5 * [tex]20\frac{4}{5}[/tex] - 2 = 104 - 2 = 102

The environmental club at Paul sells gum and candy bars as a fundraiser. One afternoon, they sold $200 worth of candy. They need to report how many of each item they sold for their club records. Maura knows that they sold 295 items that day. Candy bars sell for 75 cents, and gum sells for 50 cents. How many candy bars and gums did Paul sell?
Answer:
210 candy bars
85 gum
Step-by-step explanation:
$200=0.75cb+0.50gum
cb+gum=295
gum=295-cb
substitute
$200=0.75cb+0.50(295-cb)
$200=0.75cb+147.5-0.50cb
$200=0.25cb+147.5
0.25cb=52.5
cb=210
gum=295-210=85

A triangle has side lengths of (2u-4v)(2u−4v) centimeters, (10u+2w)(10u+2w) centimeters, and (w-7v)(w−7v) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?
Answer:
3w−11v+12u
Step-by-step explanation:
2u−4v+10u+2w+w−7v
2u-4v+10u+2w+1w-7v
2u−4v+10u+2w+1w−7v
2u+10u−4v−7v+2w+1w
2u+10u −4v−7v +2w+1w
^12u ^-11v ^3w
12u -11v+3w
3w−11v+12u
The perimeter of the triangle is represented by the expression 3w−11v+12u.
What is the perimeter of the triangle?Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees. The perimeter of the triangle is defined as the sum of all the sides of the triangle.
Given that a triangle has side lengths of (2u-4v)(2u−4v) centimeters, (10u+2w)(10u+2w) centimeters, and (w-7v)(w−7v) centimeters. The perimeter of the triangle is calculated by adding all the sides of the triangle.
E = 2u−4v+10u+2w+w−7v
E = 2u-4v+10u+2w+1w-7v
E = 2u−4v+10u+2w+1w−7v
E = 2u+10u−4v−7v+2w+1w
E = 2u+10u −4v−7v +2w+1w
E = 12u -11v+3w
E = 3w−11v+12u
Therefore, the perimeter of the triangle is represented by the expression 3w−11v+12u.

Last month his total sales were $82,968.00. What was his gross monthly income last month?
Answer:
the gross monthly income last month is $3,318.92
Step-by-step explanation:
The computation of the gross monthly income last month is shown below:
= Total sales × commission percentage
= $82,968 × 4%
= $3,318.92
