Answer:
4091
Step-by-step explanation:
Given the equation;
3x + 7x − 28 + 31 − 8x
First, we would collect like terms;
3x + 7x − 8x − 28 + 31
Simplifying, we have;
[tex] 2x + 5[/tex]
For x = 2043;
2(2043) + 5 = 4086 + 5 = 4091.
Emily works at a fast food outlet. Every week she splits her wages between savings and spending money in the ratio of 2:7 Last week she earned £144. What was Emily’s split between savings and spending money?
Answer:
His savings be $32 and spendings be $112.
Step-by-step explanation:
Let her savings and spending be 2x and 7x.
Total earning is equal to the sum of savings and spending.
ATQ,
2x+7x=144
9x=144
x = 16
Savings = 2x = 2(16) = $32
Spendings = 7x = 7(16) = $112
Hence, his savings be $32 and spendings be $112.

Find the missing number! Super easy, just don't feel like doing it, plus busy with other work.
Answer:
y = 1.37
Step-by-step explanation:
30y = 41.10
divide both sides of the equation by 30
30y/30 = 41.10/30
y = 41.10/30
y = 1.37

Write an equation through the point (4,8) that is parallel to y=5x-9
Answer:
Y=5x - 12
Step-by-step explanation:
Take a point as (x,y) on the (4,8) line,
The slope of equation is 5,
[tex] \frac{y - 8}{x - 4} = 5[/tex]
Y-8 =5x-20
Y= 5x - 12
Given collinear points E, F and G such that point F is the midpoint of segment EG. Find the new length of EG given that EF =5x+9 and FG = 3x +17
Answer:
The length of EG is 58 units
Step-by-step explanation:
The midpoint of a segment divides it into two equal part
Let us use this rule to solve our question
∵ E, F, and G are collinear points
∵ Point F is the midpoint of segment EG
→ That means F divides EG into 2 equal segments EF and FG
∴ EF = FG
∵ EF = 5x + 9
∵ FG = 3x + 17
→ Equate them
∴ 5x + 9 = 3x + 17
→ Subtract 3x from both sides
∵ 5x - 3x + 9 = 3x - 3x + 17
∴ 2x + 9 = 17
→ Subtract 9 from both sides
∴ 2x + 9 - 9 = 17 - 9
∴ 2x = 8
→ Divide both sides by 2 to find x
∵ [tex]\frac{2x}{2}=\frac{8}{2}[/tex]
∴ x = 4
→ Substitute x by 4 in EF and FG to find their lengths
∵ EF = 5(4) + 9 = 20 + 9 = 29
∵ FG = 3(4) + 17 = 12 = 17 = 29
∵ EG = EF + FG
∴ EG = 29 + 29 = 58
∴ The length of EG is 58 units
What is the volume of the figure below, which is composed of two cubes with side lengths of 9 units?
A.
54 cubic units
B.
729 cubic units
C.
1,458 cubic units
D.
810 cubic units
Answer:
C. 1458 cubic units
Step-by-step explanation:
one cubes side length is 9. The only side that changes is the length since the size is doubled so instead of it 9 it would be 18.
V= L × W × H
= 18 × 9 × 9
= 1,458

- a motorcycle driver travels 15kph faster than a bicycle rider. the motorcycle driver covers 60km in two hours less than the time it takes the bicycle rider to travel the same distance.
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Motorcycle driver travels 15kph faster than a bicycle rider
Motorcycle covers 60km in 2 hours less than the time it takes bicycle rider to travel the same distance ;
Let bicycle rider's speed = r kph
Motorcycle driver's speed = (15 + r) kph
TIME it takes bicycle rider to cover a distance of 60km = t hours
TIME it takes motorcycle driver to cover a distance of 60km = (t - 2) hours

Derek wants to order some roses online. Florist A charges $4.75 per blue
rose plus $40 delivery charge. Florist B charges $5.15 per red rose plus $25
delivery charge. If Florist B increases the cost per rose to $5.20, for what
number of roses is it less expensive to order from Florist A? From Florist B?
Step-by-step explanation:
let the total charge be y
and the number of rose be x
Florist A charges
y=40+4.75x---------1
Florist B charges
y=25+5.2x--------2
to solve for the number of roses we need to equate 1 and 2
40+4.75x=25+5.2x
40-25=5.2x-4.75x
15=0.45x
x=15/0.45
x=33.33
The number of roses that will be less expensive to order from A is 33.33
Answer:
Step-by-step explanation:
33.33

Determine the mass of a solid steel ball that has a diameter of 10 cm. The density of pure steel is 8.09 g/cm3
Answer:
The mass of the steel ball is 4,235.9 gr
Step-by-step explanation:
Density
The density ρ of a substance is a measure of its mass per unit volume:
[tex]\displaystyle \rho=\frac{m}{V}[/tex]
If the density and the volume are given, the mass can be calculated by solving the above formula for m:
[tex]m=\rho.V[/tex]
We know the density of pure steel ρ=8.09 gr/cm3 and the diameter of a solid steel ball d=10 cm.
We need to calculate the volume of the sphere:
The volume of a sphere of radius r is given by:
[tex]\displaystyle V=\frac{4}{3}\cdot \pi\cdot r^3[/tex]
The radius is half the diameter: r= 10/2 = 5 cm. Thus:
[tex]\displaystyle V=\frac{4}{3}\cdot \pi\cdot 5^3[/tex]
Calculating:
[tex]V=523.6\ cm^3[/tex]
The mass is:
[tex]m=8.09 gr/cm^3 \cdot 523.6\ cm^3[/tex]
m=4,235.9 gr
The mass of the steel ball is 4,235.9 gr
