Drag and drop numbers into the boxes to complete and solve the equation for the situation. One month, Ruby worked 6 hours more than Isaac, and Svetlana worked 4 times as many hours as Ruby. Together they worked 126 hours. Find the number of hours each person worked. h + parenleftzeh + parenrightze + parenleftzeh + parenrightze = 126 Isaac worked hours. Ruby worked hours. Svetlana worked hours.
Answer:
Ruby = x = 22 hours
Isaac = y = 16 hours
Svetlana = 88 hours
Step-by-step explanation:
Let the number of hours worked be represented as:
Ruby = x
Isaac = y
Svetlana = z
Total number of hours worked =
x + y + z = 126 hours........ Equation 1
Ruby worked 6 hours more than Isaac,
x = y + 6..... Equation 2
Svetlana worked 4 times as many hours as Ruby
z = 4 × x
z = 4x
z = 4(y + 6)
z = 4y + 24....... Equation 3
Substituting y + 6 for x and 4y + 24 for z in Equation 1
x + y + z = 126 hours........ Equation 1
y + 6 + y + 4y + 24 = 126
Collect like terms
y + y + 4y + 6 + 24 = 126
6y + 30 = 126
6y = 126 - 30
6y = 96
Divide both sides by 6
6y/6 = 96/6
y = 16
Since y represents the number of hours Isaac worked, Isaac worked for 16 hours
Substitute 16 for y in equation 2
x = y + 6
x = 16 + 6
x = 22
Since x represents the number of hours Ruby worked, Ruby worked for 22 hours
Substitute 16 for y in equation 3
z = 4y + 24
z = 4 × 16 + 24
z = 64 + 24
z = 88
Since z represents the number of hours Svetlana worked, Svetlana worked for 88 hours
Therefore:
Ruby worked for 22 hours
Isaac worked for 16 hours
Svetlana worked for 88 hours
Determine the slope of the line that passes through the points (-2, 5) (1, -7)
Answer:
-4Step-by-step explanation:
Given points
(-2, 5) (1, -7)Use slope formula to find the slope
m = (y2 - y1)/(x2 - x1)m = (-7 -5)/(1 + 2) = -12/3 = -4Slope is -4
Answer:
slope is -4
Step-by-step explanation:
Find slope which is also referred to as m:
m = (y₂ - y₁) / (X₂ - X₁)
= (-7 - 5) / (1 - (-2)
= -12 / 3
m = -4
Not asked in question but if you want to find equation for the line:
Find b using any one of the two provided coordinates. Let's use (-2, 5).
y = mx + b
5 = -4(-2) + b
5 = 8 + b
b = -3
Use m and b to make equation.
y = mx + b
y = -4x - 3

Answer:
35 they are alternate interior angles.
Step-by-step explanation:
Angle is alternate interior with angle 2 so it would be same measure in most cases. They are congruent so it would be the same measure equaling 35 degrees.
solve 0=12x^2+16x+5 by factoring
Answer: X= -1/2, X= -5/6
Step-by-step explanation:
0=12x^2+16x+5
Move all terms to the left:
0-(12x^2+16x+5)=0
Add all the numbers together, and all the variables
-(12x^2+16x+5)=0
Get rid of parenthesis
-12x^2-16x-5=0
a = -12; b = -16; c = -5;
Δ = b2-4ac
Δ = -162-4·(-12)·(-5)
Δ = 16
The delta value is higher than zero, so the equation has two solutions
Use following formulas to calculate:
x1=−b−Δ√2ax2=−b+Δ√2a
Δ−−√=16−−√=4
-> x1=−b−Δ√2a=−(−16)−42∗−12=12−24=−1/2
-> x2=−b+Δ√2a=−(−16)+42∗−12=20−24=−5/6

Answer:
111°
Explanation:
Based on the F angles theorem, ∠ABH = ∠BFE = 69°,
and based on BE ≅ BF, ∠BEF must also be 69°.
∠DEB is supplementary to ∠BEF, so
∠DEB = 180 - 69 = 111.

Elaine scored 19 out of 24 on her science test.
Addison had 81.25% on the same test.
Who did better?
How do you know?
Answer:
Addison scored a better score on the test.
Step-by-step explanation:
Elaine's score can be found by dividing 19 by 24, which yields a result of 0.7916, which means her score is a 79 out of 100 (79%). Her score can also be found by doing 100/24 = 4.16666 repeating and multiplying that by 19, which also yields 79.6. Hope this helps!

At Fruits R Us, Mr. Orchard realizes that dried pineapple slices and dried apricots were two of his top dried fruit sellers. So he decided to make a mixture of the two. The dried pineapple slices sell for $5 per pound and the dried apricots sell for $8 per pound. If the store owner wants to make 300 pounds of the fruit mixture to sell at $7 per pound, how much of each type of fruit should be used to make the mixture.
Answer:
Step-by-step explanation:
From the information given, you can write the following equations:
x+y=300 (1)
5x+8y=300*7
5x+8y=2100(2)
First, you can isolate x in (1):
x=300-y (3)
Now, you can replace (3) in (2):
5(300-y)+8y=2100
1500-5y+8y=2100
3y=2100-1500
y=600/3
y=200
Then, you can replace the value of y in (3) to find x:
x=300-200
x=100
According to this, the answer is that he should use 100 pounds of dried pineapple and 200 pounds of dried apricots.
