Answer:
3x-2y=17........(1)
x=4y-1
substituting value of x in equation 1
3(4y-1)-2y=17
12y-3-2y=17
10y=17+3
y=20/10=2
again
substituting value of y in equation 1
3x-2×2=17
3x=17+4
x=21/3=7
:.x=7,y=2

B. 25°
C. 108°
D. 130°
Answers
Answer:
90 degrees
Step-by-step explanation:
A triangle's degrees add up to 180. You are already given 2 of the. Let x be the 3rd angle. Here is the equation: 29+61+x=18. x=90.
Hope this helped!
Answer:
A.90°
Step-by-step explanation:
A triangle's interior angles are equal to 180°.
So since two angles are given all you need to do is add the given angles and subtract the sum from 180°.
61°+29°=90°
180°-90°=90°
The missing angle m<R is equal to 90°
Your answer is: A.90°

3 minutes to get them into the classroom. What Is Lucas's speed and how much work is done? Be sure to show your
work with equations as part of your answer.
Answers
12mph
Step-by-step explanation:
180 divided by 15 is 12
speed = time ÷ distance
ANSWER: speed = 5
work = 450
EXPLANATION:
Before starting to figure out this equation we must get rid of all the unneeded information. Here is a problem, Lucas is carrying his rock collection into class. He carries 30 pounds of rare rocks 15 feet into Classroom 6. It takes him 3 minutes to get them into the classroom. What is Lucas's speed and how much work is done? The unneeded information is highlighted. Now we can begin! First we must figure out Lucas speed. The equation for speed is,
Speed = distance / time. The distance is 15 feet and the time is 3 minutes. 15 / 3 = 5. Now we must figure out how much work is done. The equation for work is: Work = force x distance. The force in this equation is 30 lb And the distance is 15 ft. 30 x 15 = 450

Darnell's truck can travel 18 miles on 1 gallon of gasoline. How many gallons of gasoline will Darnell need to travel 315 miles? Use the formula d/m=g, where m represents miles per gallon, d is distance traveled, and g is the number of gallons of gasoline used.
Answers
Answer: 17.5 gallons
Step-by-step explanation:
The formula to solve this question will be: g = d/m
where, g = number of gallons of gasoline used
d = distance travelled = 315 miles
m = miles per gallon = 18 miles/gallon
Therefore, the number of gallons of gasoline that Darnell will need to travel 315 miles will be:
g = d/m
g = 315/18
= 17.5 gallons

Answers
Answer: -x + 2
Step-by-step explanation:
So I assume that the question would be set up like this if you are finding the sum of all 3 terms:
(x + 5) + (-4x - 2) + (2x - 1)
1) Take out parentheses
x + 5 - 4x - 2 + 2x - 1
2) Add like terms
For the x terms:
x - 4x = -3x
-3x + 2x = -x
For the other terms:
5 - 2 = 3
3 - 1 = 2
The sum of the terms is -x + 2
