2x -10 = 3x +6 -4x +8
3x=24
x=8
Answer:
x = 8 (d)
Step-by-step explanation:
Expand
2x - 10 = 3x + 6 - 4x + 8
Collect like terms
2x - 3x + 4x = 6 + 8 + 10
3x = 24
Divide both sides by 3 to make x on its own
x = 8

An automobile manufacturer is preparing a shipment of cars and trucks on a cargo ship that can carry 21,600 Tons. The cars weigh 3.6 tons each and the trucks weigh 7.5 tons each. For a different shipment, cars are loaded first, and then trucks are loaded afterwards. Write an equation you could enter into a calculator or a spreadsheet tool to find the number of trucks that can be shipped if the number of cars is known. Let x=number of cars (input) and Let y=number of trucks (output)
Answers
Answer:
Number of trucks (y) that can be shipped if the number of cars (x) is known[tex]=\frac{21,600-3.6x}{7.5}[/tex]
Step-by-step explanation:
A cargo ship can carry 21,600 Tons.
Let x denotes number of cars and y denotes number of trucks.
The cars weigh 3.6 tons each and the trucks weigh 7.5 tons each.
Therefore,
[tex]3.6x+7.5y=21,600[/tex]
Now write y in terms of x.
[tex]7.5y=21,600-3.6x\\y=\frac{21,600-3.6x}{7.5}[/tex]
Number of trucks (y) that can be shipped if the number of cars (x) is known[tex]=\frac{21,600-3.6x}{7.5}[/tex]

Answers
Given parameters:
Length of the gift box = 8 inches
Width of the box = 3 inches
Height of the box = 4 inches
Unknown :
Length of its longest diagonal = ?
Solution:
This is a rectangular box.
To find the diagonal of such box, let us use the formula below;
Diagonal = [tex]\sqrt{l^{2} + w^{2} + h^{2} }[/tex]
l is the length
w is the width
h is the height
Input the parameters and solve;
Diagonal = [tex]\sqrt{8^{2} + 3^{2} + 4^{2} }[/tex] = 9.4inches
The diagonal of the box is 9.4inches

Answers
Answer:
0.0390cm/minStep-by-step explanation:
We are expected to do a unit conversion here.
let us convert days to minutes first
6.5days to minutes
1 day has 1440miuntes
6.5 days has x minute
cross multiply we have
x=6.5x1440
x=9360minute
let us convert yards to cm
1 yard to 91.44 cm
4 yards has xcm
cross multiply we have
x=4x91.44
x=365.76cm
the speed in cm per mins is
speed=365.76/9360m
speed=0.0390cm/min

If a point (x,y) is rotated 90 degrees counterclockwise around the origin, what will the resulting coordinate be?
Answers
Answer:
Step-by-step explanation:
90 degrees clockwise will result in a (+,+) answer.
90 degrees counterclockwise will result in a (-,+) answer.
Think of your quadrants.
Quadrant 1 the answer will be (+,+)
Quadrant 2 the answer will be (-,+)
Quadrant 3 the answer will be (-,-)
Quadrant 4 the answer will be (+,-)
It all depends where you are starting, so if you have to go counter clockwise from the third quadrant, your answer will be a coordinate that is (+,-).
