Answer:
(3,7)
Step-by-step explanation:
x-3y=-2 -----equation i
x+3y=16-----equation ii
Subtract the two equations from each other
-6y=-18
-6y/-6=-18/-6
y=3
Substitute for x in equation i
x-3(3)=-2
x-9=-2
x=-2+9
x=7
x=7,y=3
Answer:
X is 7, and Y is 3.
Step-by-step explanation:
Step 1: Add 3y to both sides
x - 3y + 3y = -2 + 3y
x = 3y - 2
Step 2: Substitute 3y - 2 for x in x + 3y = 16
x + 3y = 16
3y - 2 + 3y = 16
Step 3: Simplify both sides of equation
6y - 2 = 16
Step 4: Add 2 to both sides
6y - 2 + 2 = 16 + 2
6y = 18
Step 5: Divide both sides by 6
6y/6 = 18/6
y = 3
Step 6: Substitute 3 for y in x - 3y = -2
x - 3(3) = -2
Step 7: Multiply 3 by 3 for 9
x - 9 = 2
Step 8: Switch sides!
x = 9 - 2
Step 9: Subtract 9 minus 2 to get 7
x = 7
With that we have our final answers: x = 7, and y = 3.

The ratio of money in Brian's wallet to Colin's wallet one day was 7:2.
Brian spent £39 that day.
Brian now had £4 less than Colin.
How much did they initially have altogether?
Answer:
£30
Step-by-step explanation:
Let Brian initially had money in his wallet = £x
and Colin had the money = £y
Since ratio of money in Brian's wallet to Colin's wallet was 5 : 1
Therefore,
⇒ x = 5y -------(1)
Brian spent £27 that day, so money left with him = £(x - 27)
After spending the money Brian had £3 less than Colin.
(x - 27) = (y - 3)
x = y + 27 - 3
x = y + 24 -------(2)
Now we equate the equations (1) and (2) for the value of x,
5y = y + 24
5y - y = 24
4y = 24
y = £6
From equation (2),
x = 6 + 24
x = £30
Therefore, Brian initially had £30.

Angela purchased a storage cube with a volume of 10 cubic feet. She wants to put it on a shelf that is 24 inches tall.
A.
Yes, because the height of the cube is approximately 4.93 inches.
B.
Yes, because the height of the cube is approximately 2.15 inches.
C.
No, because the height of the cube is approximately 25.85 inches.
D.
No, because the height of the cube is approximately 39.96 inches.
Answer:
c
Step-by-step explanation:
10 cubic feets volume is equivilant o 25.85 inches.
No, because the height of the cube is approximately 25.85 inches. Option C is correct.
What is volume?It is defined as a three-dimensional space enclosed by an object or thing. A cube's volume can be calculated using its side cube.
Given that, Angela bought a storage unit with a 10 cubic foot capacity. It will go on a shelf that is 24 inches tall,
Volume, V = 10 cubic feet
Height, h =24 inches
The volume of a cube is found as the cube of the side.
Volume of cube = side³
V=a³
10=a³
Take a cube root of 10 to find the value of a,
a=2.15 feet
We can convert feet into inches, in one foot there are 12 inches.
1 feet = 12 inches
2.15 feet = 2.15 × 12
2.15 feet = 25.85 inches
Thus, no because the height of the cube is approximately 25.85 inches. Option C is correct.

Lanya's house is located at (2 2/3, 7 1/3) on a map. The store where she works is located at (-1 1/3, 7 1/3). what is the distance from Lanya's home to the store?
Answer:
Option A: 4 units is the correct answer.
Step-by-step explanation:
Given that:
Layana's house is located at ([tex]2\frac{2}{3}, 7\frac{1}{3}[/tex])
Store is located at ([tex]-1\frac{1}{3},7\frac{1}3}[/tex])
We can find distance between two points by using distance formula.
S = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
The points can also be written as;
House (8/3, 22/3)
Store (-4/3, 22/3)
Putting values in the formula.
S = [tex]\sqrt{\frac{8}{3}-(-\frac{4}{3}))^2+(\frac{22}{3}-\frac{22}{3})^2[/tex]
S = [tex]\sqrt(\frac{8}{3}+\frac{4}{3}+0[/tex]
S = [tex]\sqrt{(\frac{8+4}{3})^2[/tex]
S = [tex]\sqrt{(\frac{12}{4})^2[/tex]
S = [tex]\sqrt{(4)^2[/tex]
S = 4 units
Hence,
Option A: 4 units is the correct answer.

Step-by-step explanation:
distribute on the left side first:
-4(3k-6)-4k

combine like terms
-16k+24
now the right side
-8k+24-4k
combine like terms
-12k+24
so it'll look like this
-16k+24=-12k+24
add -12k to the left
