Solve for b. b + 2 = 4.6
b=6.6
b=4.12
b=2.6
b=2.3
Answer:
b=2.6
Step-by-step explanation:
b+2=4.6
Subtract both sides by 2 to isolate b
b+2-2=4.6-2
b=2.6
Therefore, b is equal to 2.6.

Step-by-step explanation:
- 3(x - 7) + 2 = 20 I need help to solve it
Answer:
x=1
Step-by-step explanation:
First you will distribute it
U basically multiply the 3 by the X and the 7 here
-3 x (x = -3x And the 7 becomes a 21
Then you add the 2
21 + 2 = 23
Then you add the -3
-3x + 23 =20
Then using the equation above you subtract 23 from both sides
(-3 + 23) - 23 = 20 - 23
Then you simplify it
-3x = -3
Then you divide them using the same term
-3
÷ -3
Then you simplfy it and you get
x=1
Joe works for a charity. Each year the charity gives money to different projects. The charity has a total of eight thousand nine hundred and sixty-eight pounds to give to the projects this year.
Answer:
[tex]Each =\pounds 1121[/tex]
Step-by-step explanation:
See comment for complete question.
Given
[tex]Total = \pounds 8968[/tex]
[tex]Projects = 8[/tex]
Required
Determine the amount allotted to each
From the question, we understand that each project gets each allocation.
So, the amount of each is:
[tex]Each =\frac{Total}{Projects}[/tex]
[tex]Each =\frac{\pounds 8968}{8}[/tex]
[tex]Each =\pounds 1121[/tex]
Each project gets £1121
If 6 cakes cost £1.80, how much do 4 cost
Write an equation in slope-intercept form of the line shown.
Answer:
y=2x-2
Step-by-step explanation:
The slope is 2 and your y intercept is already given as -2.
Slope intercept is basically y=mx+b
plug it in so you get y=2x-2
A father is 20 years older than his son. Five years ago,he was three times as old as his son was.Find their present ages
Answer:
Dad=35, Son=15
Step-by-step explanation:
Well since the dad is 20 year older then the son we can call the son x and the dad x+20. Now five years ago the father was 3 times older then the so we construct the following equation:
x+20−5=3(x−5)
x+15=3x-15
x=15
So now we know that the sons age is 15 meanimg that since the dads 20 years older then him, his age is 20+15 which is 35!
For each fraction, select the most appropriate estimate. 36 40 choose.. 1 3 choose.. 70 100 choose.. 1 8 choose.. Options: Closest to 0 Closest to one half Closest to 1
Answer:
Convert each fraction to its percentage form:
= 36 / 40
= 90%
= 1/3
= 33.3%
= 70/100
= 70%
= 1 / 8
= 12.5%
Looking at the percentages:
= 36 / 40 is closest to 1.
= 1/3 and 70/100 are closest to one half which is 50%
= 1/8 is closest to 0.
Explain how you would find 90% of 120 will give brainliest if correct

Find the exact value of cos0. Express your answer as a fraction.
Trigonometric Functions -
[tex] \cos = \frac{adjacent}{hypotenuse} [/tex]
Find the opposite side, first of all.
Pythagorean Theorem -
[tex]a^{2} + b^{2} = c^{2} [/tex]
Input the hypotenuse and opposite sides to find b^2.
[tex]49 + {b}^{2} = 64[/tex]
Minus 49 from equations to get b^2 by itself.
[tex] {b}^{2} = 15[/tex]
Square root b^2 and 15 to get b by itself.
[tex]b = \sqrt{15} [/tex]
Now we can get to the trigonometry functioms!
[tex] \frac{ \sqrt{15} }{8} [/tex]
Divide them up, then find the percentage!
48% or...
[tex] \frac{ \sqrt{15} }{8} [/tex]
The combined height of one fur tree and one pine tree is 21 meters. The higher of 4 fir trees stacked on top of each other is 24 meters taller that the one pine tree. How tall are the types of trees that Logan genetically engineered?
Answer: Fur tree = 6 meters, pine tree = 15 meters
Step-by-step explanation:
Lets say the height of one fur tree is x
the height of one pine tree is y
so x+y=21 and 4x=24
x = 6
y = 15

Find the total surface area of a cuboid whose length,breadth,and height are 9cm,7cm,and 4cm respectively.pls help me guys.and I will make you brainliest.it is not false I am saying true
Answer:
length=9 cm breadth=7cm height=4cm area of a cubid=: we know that area of a cuboid= 252
Answer:
254
Step-by-step explanation:
Length : a
Width : b
Height : c
Surface : s
s = 2(ab + bc + ca)
s = 2(9x7 + 7x4 + 4x9)
s = 2(63 + 28 + 36)
s = 2(127)
s = 2 x 127
s = 254

An angle measures 56° more than the measure of its supplementary angle. What is the measure of each angle?
Answer:
62,118
Step-by-step explanation:
Let one angle = x
So, other angle = x +56
x +x +56 = 180 {Combine like terms}
2x + 5 6 = 180 {Subtract 56 form both sides}
2x = 180 - 56
2x = 124 {Divide both sides by 2}
x = 124/2
x = 62
Other angle = 62 + 56 = 118
8x^{3}-7x^{3}+16x^{3}
combining like terms
Answer:
17x^3
Step-by-step explanation:
8-7+16=17 keep the like terms

Answer:$25.50
Step-by-step explanation:
Convert the problem to an equation using the percentage formula: P% * X = Y.
P is 10%, X is 150, so the equation is 10% * 150 = Y.
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10. Im not sure if this is the nearest cent but here are the steps to find the nearest cent.
