Answer:
x=0.7x+24
We move all terms to the left:
x-(0.7x+24)=0
We get rid of parentheses
x-0.7x-24=0
We add all the numbers together, and all the variables
0.3x-24=0
We move all terms containing x to the left, all other terms to the right
0.3x=24
x=24/0.3
x=80
And that's how you get 80
Step-by-step explanation:
i hope this helps. :)
Answer: x = 80
Step-by-step explanation:
80 - 24 = 56
56 divided by 0.7 = 80

John needs to wrap the edge of his rectangular desk with duct tape. He knows the width is 10/8 of a meter and the length is 3/8 of a meter. How much duct tape does he need to wrap the desk’s perimeter?
Answer: 1 and 5/8
Step-by-step explanation:
The dimensions of a rectangle are x+3 and x+4. The area of the rectangle is 72. Set up an equation that models this rectangle and solve in order to determine the value of x.
Answer: x = 5
Step-by-step explanation:
The area of a rectangle is the length times the width. Since the dimensions are given as functions of x, youre going to have to use FOIL to combine them, then set that answer equal to the given value of 72.
l*w = (x+3)*(x+4) = x^2 + 7x +12 = 72
Subtract 72 on both sides. There is a reason why we'll do this instead of subtracting 12. The quadratic formula will help us to solve for x.
x^2 + 7x - 60 = 0
Apply the quadratic formula
[tex]\frac{-7 (+/-)\sqrt{7^2-(4)*(1)*(-60} }{2*1} =\frac{-7(+/-)17}{2}[/tex]
We cant have a negative x value because that would result in negative dimensions and a negative area, which is impossible in this context. So you want to add the 17 instead of subtracting it.
x = 5 and x = -12
An alternate way is just factoring the trinomial to:
(x+12)(x-5) = 0
Find the shaded area
Answer:
area of big rectangle=l×b=12×18=216cm²
area of smaller square=l²=8²=64cm²
area of shaded area =area of (bigger rectangle-smaller square)=216-64=152cm²

Lara eats a bowl of granola for breakfast every morning. She wonders how much granola she eats in a year. If Lara eats about one 48-ounce bag of granola every month, how many pounds of granola does she eat each year?
Answer:
36 pounds granola in a year
Step-by-step explanation:
Well there are 12 months a year.
She eats 48 ounce every month.
48 ounce = 3 pounds
3 pounds * 12 months = 36 pounds a year
//she sure does like granola o.o

The time,
T
(seconds), it takes for a pot of water to boil is proportional to the amount,
A
(litres), of water.
It takes 180 seconds to boil 2.8 litres of water.
Work out how long it takes (to the nearest second) to boil 2.2 litres.
Answer:
The time it takes to boil 2.2 litres of water is approximately 141 seconds
Step-by-step explanation:
The given parameters are;
The relationship of the variables, T and A is a proportional, therefore, we have;
T ∝ A, or T/A = k = Constant of proportionality
The time it takes to boil 2.8 liters of water = 180 seconds
∴ When A = 2.8 litres, T = 180 seconds, from which we have;
k = T/A = 180 s/(2.8 L) = 450/7 s/L
k = 450/7 s/L
When A = 2.2 litres, we have;
T/A = k
∴ T = k × A
Plugging in the value for both 'k', and 'A' when A = 2.2 litres, gives;
T = k × A = 450/7 s/L × 2.2 L = 990/7 s = 141.[tex]\overline{428571}[/tex] s
The time it takes to boil 2.2 litres of water, given a direct proportionality relation is, T = 141.[tex]\overline{428571}[/tex] seconds ≈ 141 seconds given to the nearest second.

solve for x
Answer:
X = 60°
Step-by-step explanation:
the angle you are looking for is a corresponding angle to the angle given (121°)
2x + 1 = 121
121 - 1 = 2x
121 - 1 = 120
2x = 120
120/2 = 60
X = 60

awnser im believe it is 24 i think
Answer:
20 units square
Step-by-step explanation:
do the Pythagoras theorem
a²=b²+c² ⇒ a=√b²+c²
if b is 4 and c is 2 an a is the unknown
so a=√(4)²+(2)²
a=√20
then get the rule of the area of the square
Area of the square= s²
s=a=√20 (a is the hypotenuse of the triangle and also a side in the square)
so s²=20
Area of the square=20 units square

A grocery store is offering a sale on bread and soup. Kacey buys four cans of soup and three loaves of bread for $12.35. Fernando buys eight cans of soup and one loaf of bread for $13.05. a. Write equations for both Kacey's and Fernando's purchases.
Answer:
[tex]4x+3y=12.35-------------1\\\\x+8y= 13..05-------------2[/tex]
Step-by-step explanation:
Given data
let bread be x
and soup be y
Kacey buys four cans of soup and three loaves of bread for $12.35
4x+3y=12.35-------------1
Fernando buys eight cans of soup and one loaf of bread for $13.05
x+8y= 13..05-------------2
Hence the equation for both of their purchase is [tex]4x+3y=12.35-------------1\\\\x+8y= 13..05-------------2[/tex]
