What is the value of y in the solution to the following system of equations?
5x - 3y = -11
2x - 5y = -14 (1 point)
O-1
OO
1
2
Answer:
Option D is the correct answer.
Step-by-step explanation:
The equations are:
5x - 3y = -11 Eqn 1
2x - 6y = -14 Eqn 2
We have to find the value of y so we will eliminate x.
Multiplying Eqn 1 by 2
2(5x-3y=-11)
10x-6y=-22 Eqn 3
Multiplying Eqn 2 by 5
5(2x-6y=-14)
10x-30y=-70 Eqn 4
Subtracting Eqn 4 from Eqn 3
(10x-6y)-(10x-30y)= -22-(-70)
10x-6y-10x+30y = -22 + 70
24y = 48
[tex]\frac{24y}{24}=\frac{48}{24}\\y=2[/tex]
Therefore,
Option D is the correct answer.

base of a triangle is four times the height if the area is 338 feet then what is the height of the triangle in feet
Answer:
h = 13 feet
Step-by-step explanation:
A = bh ÷ 2
base (b) = 4h
338 = 4h(h) ÷ 2
338 = 2h²
169 = h²
√169 = h
13 = h

The amount of time it takes Isabella to wait for the bus is continuous and uniformly distributed between 4 minutes and 18 minutes. What is the probability that it takes Isabella more than 7 minutes to wait for the bus
Answer:
0.25 or 25% probability
Step-by-step explanation:
The lower limit in this question = a
The upper limit = b
P(X<=x) = x-a/b-a
a = 4
b = 8
The question says it is uniformly distributed between 4 minutes and 8 minutes
Probability that it takes her more than 7 minutes to wait for the bus
P(X<=7) + P(X>7)= 1
We are to get P(X>7)
= 1 - (7-4/8-4)
= 1-3/4
= 1-0.75
= 0.25
= 25% probability it takes her more than 7 minutes to wait

Judy is selling small candles at the fair for $4 each and large candles for $6 each. She collected $144 selling a total of 28 candles. How many of each candle did she sell? Use x for the small candles and y for the large candles.
small candle x= blank candles
large candle y = blank candles
Answer:
Number of small candles = 12
Number of large candles = 16
Step-by-step explanation:
Total candles = 28
x + y = 28 ---------------(I)
Cost of 'x' small candles = 4 *x = 4x
Cost of 'y' large candles = 6 *y = 6y
Total amount = $144
4x + 6y = 144 -------------(II)
Multiply equation (I) by (-4) and then add the equation. So, x will be eliminated and we can find the value of 'y'
(I) * (-4) -4x - 4y = -112
(II) 4x + 6y = 144 {Now, add}
2y = 32
y = 32/2
y = 16
Plug in y = 16 in equation (I)
x + 16 = 28
x = 28 - 16
x = 12
Answer:
small candles-x
large -y
144-4x=6y
28-x=y
28-y=x
(28-x)6+4x=144
168-6x+4x=114
-2x=-54
2x=54
x=27
27 small and 1 large

The restaurant sold coffee and tea during the breakfast shift. The number of cups of tea they sold was 6 more than 1/3 of the number of cups of coffee sold. If the total cups of coffee and tea sold was 70, how many cups of each were sold?
Answer:
cups of tea = 22
cups of coffee = 48
Step-by-step explanation:
c = coffee
t (tea) = 6 + 1/3c
t + c = 70
c + 6 + 1/3c = 70
4/3c + 6 = 70
4/3c = 64
4c = 192
c = 48
t = 70 - 48 = 22

The area of a rectangular dining room is 16 square meters. The perimeter is 16 meters. What are the dimensions of the dining room?
Answer:
4
Step-by-step explanation:
The area is 16, and you know that it's 2 sides u need to multiply
The perimeter is 16, and you know that you need to add up all the sides
So....
A = b * h
A = 4 * 4
A = 16 CORRECT
And....
P = S + S + S + S ( s = sides)
P = 4 + 4 + 4 + 4
P = 16 CORRECT

Patty wants a triangle garden in her backyard for all of her vegetables. She
is going to use three pieces of fencing that measure 7 feet, 10 feet, and 8
feet. Will her garden be in the shape of a right triangle? Why or why not?
Answer:
Step-by-step explanation:
the hypothenuse is the largest side in the right triangle
we have 2 side, 7,8
in a right triangle, c^2= a^2+b^2
where c is the hypothenuse
c^2=49+64=113
c=sqrt113=aprox 10.6
so, the answer is no if it has to be exactly 10 ft the hypotenuse
