solve 3x − 2y = −21 and 2x + 5y = 5 using elimination
Answer:
x = -5 and y = 3
Step-by-step explanation:
There are two equations :
3x − 2y = −21 ....(1)
2x + 5y = 5 ......(2)
Multiply equation (1) by 2 and equation (2) by 3.
6x - 4y = -42 ...(3)
6x + 15y = 15 ....(4)
Subtract equation (4) from (3) :
6x - 4y - (6x + 15y) = -42 -15
-4y -15y = -57
-19y = -57
y = 3
Put y = 3 in equation (2) :
2x + 5(3) = 5
2x = 5-15
2x = -10
x = -5
So, the value of x is (-5) and y = 3.
5 - (x + 1) = 5x + 4

A mixture of paint calls for 1/3 cups of red paint and 3/4 cups of yellow paint. If there were 4 cups of red paint added to the mixture, how many cups of yellow paint would need to be added to keep a constant rate of proportionality? (Hint: You can use your answer from the first question to help you solve this!)
Answer:
9 cups of yellow paint
Step-by-step explanation:
A mixture of paint calls for 1/3 cups of red paint and 3/4 cups of yellow paint.
From the above question
1/3 cups of red paint = 3/4 cups of yellow paint
1 cup of red paint = x cups of yellow paint
Cross Multiply
1/3 × x = 3/4 × 1
x = 3/4 ÷ 1/3
x = 3/4 × 3/1
x = 9/4
x = 2 1/4 cups of yellow paint
Hence, 1 cups of red paint requires 2 1/4 cups of yellow paint
If there were 4 cups of red paint added to the mixture, how many cups of yellow paint would need to be added to keep a constant rate of proportionality?
1 cups of red paint = 2 1/4 cups of yellow paint
4 cups of red paint = x cups of yellow paint
Cross Multiply
x cups of yellow paint = 4 × 2 1/4 cups of yellow paint
= 4 × 9/4 cups of yellow paint
= 9 cups of yellow paint
Therefore, 4 cups of red paint requires 9 cups of yellow paint

A boat on a river travels downstream between two points, 90 mi apart, in 1 h. The return trip against the current takes 2 1 2 h. What is the boat's speed (in still water)?
Answer:
A)63miles per hour.
B)27 miles per hour
Step-by-step explanation:
HERE IS THE COMPLETE QUESTION
boat on a river travels downstream between two points, 90 mi apart, in 1 h. The return trip against the current takes 2 1 2 h. What is the boat's speed (in still water)??b) How fast does the current in the river flow?
Let the speed of boat in still water = V(boat)
speed of current=V(current)
To calculate speed of boat downstream, we add speed of boat in still water and speed of current. This can be expressed as
[V(boat) +V(current)]
It was stated that it takes 1hour for the
boat to travels between two points of 90 mi apart downstream.
To calculate speed of boat against current, we will substact speed of current from speed of boat in still water. This can be expressed as
[V(boat) - V(current)]
and it was stated that it takes 2 1/2 for return trip against the Current
But we know but Speed= distance/time
Then if we input the stated values we have
V(boat) + V(current)]= 90/1 ---------eqn(1)
V(boat) - V(current) = 90/2.5----------eqn(2)
Adding the equations we have
V(boat) + V(current) + [V(boat) - V(current)]= 90/2.5 + 90/1
V(boat) + V(current) + V(boat) - V(current)]=90+36
2V(boat)= 126
V(boat)=63miles per hour.
Hence, Therefore, the speed of boat in still water is 63 miles per hour.
?b) How fast does the current in the river flow?
the speed of the current in the river, we can be calculated if we input V(boat)=63miles per hour. Into eqn(1)
V(boat) + V(current)]= 90/1
63+V(current)=90
V(current)= 27 miles per hour
Hence,Therefore, the speed of current is 27 miles per hour.

Answer:
x=50°
Angle at A=108°
Step-by-step explanation:
If the triangle ABC is isosceles,then <ABC=<ACB=65°
We can now use angle properties to find <BAC
<BAC+65+65=180°
<BAC=180°-130=50°
Since line AB and CD are parallel,line AC is a transversal line which means <BAC=<ACD=x=50°
Therefore x=50°
For the parallelogram,
opposite interior angles are equal so <BAD=<BCD and <ABC=<ADC
3x+3x+2x+2x=360°
10x=360°
x=360°/10=36°
The angle at a=3x=3×36°=108°

a 10-pound ice cream cake is sliced in half, and each half is then sliced into eighths. what is the weight, in ounces, of each slice of cake? (1 pound
Answer:
10 oz.
Step-by-step explanation:
There are 16 oz in 1 lb. So for the 10 lb. cake there is a total of 160 oz to start. If the cake is cut in half and then in 8 pieces. There will be a total of 16 pieces.
10 lb/whole cake
= 160 oz/2 halves
= 160 oz/16 slices
= 10 oz/slice
Each slice of icecream cake is 10 oz.

The surface area of a cylinder aluminum can is a measure of how much aluminum the can requires. If the can has radius r and height h, its surface area A and its volume V are given by the equations: A= 2πr^2 + 2πrh and V=πr^2h
a) The volume V of a 12 oz cola can is 355 cm^3. A cola can is approximately cylindrical. Express its surface area A as a function of its radius r, where r is measured in centimeters. [hint: first solve for h in terms of r.]
PLEASE HELP FAST
The required surface area would be A= 2πr² + 710/r which represents area A as a function of its radius r, where r is measured in centimeters.
The can's surface area A and volume V are determined by the equation if the container has a radius of r and a height of h.
A= 2πr² + 2πrh and V = πr²h
The volume V of a 12 oz cola can is 355 cm³
Given that cola can is approximately cylindrical.
V = πr²h = 355 cm³
h = 355 / πr²
Substitute the value of h in the can's surface area A, we get
A= 2πr² + 2πr(355 / πr²)
A= 2πr² + 2(355/r)
A= 2πr² + 710/r
Therefore, the required surface area would be A= 2πr² + 710/r which represents area A as a function of its radius r, where r is measured in centimeters.

y = 3
Answer:
y = 5
Step-by-step explanation:
when the slope of a line is 0 because it does not incline
it is y = wherever the y value is
so in this case
it is
y = 5
The equation shown models the height of a 32-inch candle after lighting it, where m represents the time the candle has been burning, in minutes, and h represents the candle's height. h=32−14m If the candle's height is now 25 inches, exactly how many minutes has it been burning?
Answer:
0.5 minutes
Step-by-step explanation:
Since we are provided the equation and the current height of the candle (which would be 25 inches) we can simply replace this current height with the variable h and then solve the rest of the equation to find out the value of m when the height of the candle is at 25 inches.
h = 32−14m
25 = 32−14m ... subtract both sides by 32
-7 = -14m ... divide both sides by -14
0.5 = m
Finally, we can see that after 0.5 minutes the candle would have melted down to 25 inches.
