Answer:
100
Step-by-step explanation:
we start by subtracting 20 from 70, which is 50
we double 50 to get 100
Answer:
n = 100
Step-by-step explanation:
20 + 1/2n = 70
subtract 20 from both sides
1/2n = 50
multiply both sides by the reciprocal of 1/2 which is 2
n = 100

1 hour is 550 miles how many miles would 1 hour and 42 minutes be
If 1 hour is 550 miles then 1 hour and 42 minutes would be 935 miles.
What is unit conversion?It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.
It is given that,
1 hour = 550 miles
As we know,
1 hour = 60 minute
60 minute = 550 miles
1 minute = 550 miles / 60
1 minute = 9.16667 miles
42 minutes = 9.16667 miles
42 minutes = 385 miles
As a result,
1 hour and 42 minutes = 550 miles + 385 miles
1 hour and 42 minutes = 935 miles.
Thus, if 1 hour is 550 miles then 1 hour and 42 minutes would be 935 miles.

Step-by-step explanation: To find the new price, we would simply perform "37 + 20%" yielding 44.4, or forty four dollars and 40 cents. Hope this answered your question.
Answer: 44.4
Step-by-step explanation:
To calculate the original price of a discounted or sale item, you need to know the sale price and the discount percentage. The calculations include a simple formula that divides the sale price by the result of 1 minus the discount in percentage form. Use this formula to calculate the original or list price of an item.
4+3(3x + 1) = 29 - 2x
Answer:
Step-by-step explanation:
4 + 9x + 3 = 29 - 2x
9x + 7 = 29 - 2x
11x = 22
x = 2
Answer:
x=2
Step-by-step explanation:
4 + 3(3x+1)=29 − 2x
4 + (3)(3x) + (3)(1)=29 + −2x
4 + 9x + 3=29 + −2x
9x + 7=−2x + 29
9x + 7 + 2x=−2x + 29 + 2x
11x + 7=29
11x+7 − 7=29 − 7
11x=22
11x /11=22/11

Which expression shows 7+21 written as a product of two factors?
(A)3(1+7)
(B)3(3+7)
(C)7(3+3)
(D)7(1+3)
Expressing or writing 7+21 as a product of two factors requires the application of Distributive Property
The expression that shows 7+21 written as a product of two factors is
7(1 + 3).
To solve the above question, we apply the Distributive property.This is expressed as:a (b + c) = ab + ac
Where
a is the common factor
We are given the expression:
7 + 21
Splitting this into two factors using the distributive property
7 + 21
The common factor for 7 and 21 is 7
Hence, by factorising we have:
7 + 21 = 7(1 + 3)
Therefore, the expression that shows 7+21 written as a product of two factors is :
7(1 + 3)
The correct option is D

pearl will put wire around a rectangular lot with a width of 20m and a length that is two times its width.how many mters of wire will she need?
Let's see what to do buddy...
_________________________________
STEP (1)
First we need to find the length.
(( length is two times the width ))
Length = 20 × 2 = 40 m
_________________________________
STEP (2)
Pearl will put wire around a rectangular.
Around of rectangular = Perimeter of it
So we must to find the perimeter of the rectangular.
[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: p = 2(length + width) \\ \\ p = 2(20 + 40) \\ \\ \: \: \: \: p = 2 \times 60 = 120[/tex]
So Pearl needs 120 meters of wire.

Un número desconocido es multiplicado por 11 y a este resultado se le resta 24. El resultado de esta operación es 86. Escribe en lenguaje algebraico la expresión anterior y contesta: ¿Cuánto vale el número desconocido?
Answer: The number is 10.
Step-by-step explanation:
Let x be the required number.
Given: 11 is multiplied to the number then 24 is subtracted from that and the result is 86.
The mathematical statement for the given situation,
11x -24 = 86
To solve the equation, Add 24 on both sides , we get
11x - 24 +24 = 86+24
⇒ 11x = 110
Divide both sides by 11, we get
x = 10
hence, the number is 10.

Determine if (3, 7) is a Solution or not Solution to the linear system.
y = 2x + 1
y = -4x + 7
Answer:
y = 2x + 1 --> linear
y = -4x + 7 --> non-linear
Not a solution for linear system.
Step-by-step explanation:
for (a), y = 2x+1, substitute the x and y values. keep in mind, that in a linear pair, (x, y). So, for the first equation you get:
7 = 2x3 + 1. This is correct, because 6 + 1 is 7. Therefore, (a) is linear.
for (b), we have to substitute our values again. You get:
7 = -4x3 + 7, which is
7 = -12+7, which is not true. So, (b) is not linear.
This means that for the linear pair (3, 7), it does not satisfy both equations, which means that it is not a solution for the linear system.
