Answer:
Answer 4, the bottom right answer
Step-by-step explanation:
Question was pretty blurry so I had to write it out:
The school Spanish Club is holding a car wash to raise $200 to attend a conference. After spending $10 on supplies, the club will was cars for donations of $4 each.
The situation can be modeled by the inequality 4z-10≥200, which has the solution z≥52.5. What is the best way to interpret this solution?
1. At least 53 members of the Spanish Club must volunteer to help at the car wash.
2. The Spanish Club should have spent at least $52.50 on supplies.
3. The Spanish Club needs $52.50 more to meet its goal.
4. The Spanish Club must wash at least 53 cars to meet its goal.
The answer would be 4, because the inequality is saying 4 dollars times the number of cars minus 10 dollars (for supplies) has to be greater than or equal to their goal of 200 dollars they want to raise.
Another way to explain: The 4z would represent how much money they would make for all the cars they wash, but they have to subtract 10 dollars for the supplies. This total has to be equal to or more than their goal of 200 dollars.
Answer:
a) 0≠ -10
b) x= -3
c)y= 0
Step-by-step explanation:
a) 3-4x=-7-4x
So, this equation has no solution as both sides are not equal.
b) 
Solving:
So, this equation has one solution
c) 7(y-3)=6y-21
Solving:
So, this equation has one solution.
1. Write equation with no solution. 3-4x=-7-4x (check solution of a)
2. Write equation with one solution. 7(y-3)=6y-21 (check solution of c)
3. Write equation with infinite solution. 2x + 3 = x + x + 3
solving:
2x+3=2x+3
2x-2x+3=3
3=3
When both sides are equal, the equation has infinite solutions.
The measurement of angle L = 50°.
Solution:
The given image is a rectangle.
The measurement of ∠A = 25°
The measurement of ∠B = 25°
ABC is a triangle.
Sum of the interior angles of the triangle = 180°
⇒ m∠A + m∠B + m∠C = 180°
⇒ 25° + 25° + m∠C = 180°
⇒ 50° + m∠C = 180°
⇒ m∠C = 180° – 50°
⇒ m∠C = 130°
Sum of the adjacent angles in a straight line = 180°
⇒ m∠C + m∠L = 180°
⇒ 130° + m∠L = 180°
⇒ m∠L = 180° – 130°
⇒ m∠L = 50°
Hence the measurement of angle L = 50°.
Answer:
ill explain better
Step-by-step explanation:
use distrubrity property and you get 6x + 6x -18y+6+(-9) then you add 18 because you have to get the y way so you do the opposite of subtracting which is adding so when you add the 18 to it self you then add the 18 to one of the 6x the you get 24x+6x+-4 which u add 6 to -9 the to combine like terms and get 30x+-4
Answer:
1. x = 10 , y = 2
