Tony’s class needs more than $500 for the school dance. So far, they have raised $200. They plan to have a car wash, charging $8 a car, to raise more money. Tony solved the inequality 8x + 200 Greater-than-or-equal-to 500, and determined that if they wash 37 cars, they will have enough money. Is he correct? Explain

Answer:

y = 3x + 74

Step-by-step explanation:

Answer:

X+2y=4

4+2y=x

2(2+y)=x

2x-2y=5

2(x-y)=5

x-y=5/2

Answer:

(x, y) = (3, 1/2)

Step-by-step explanation:

x + 2y = 4

2x - 2y = 5

There is more than one way to do this. I will do it by substitution.

From the first equation, x + 2y = 4, so x = (-2y) + 4

Now, in the second equation, I will replace x with (-2y + 4)

2(-2y + 4) - 2y = 5

-4y + 8 -2y = 5

-6y + 8 = 5

-6y = -3

6y = 3

y = 3/6

--------------------------------->  y = 1/2, one part of the answer

Now I can go back to the first equation, and relpace 'y' with 1/2

x + 2(1/2) = 4

x + 1 = 4

----------------------------------->  x = 3, the other part of the answer

So now we believe the solution is (x, y) = (3, 1/2)

Now check the answer, back in the original equations!!

------> In the first equation, we would have 3 + 2(1/2) = 4.

                                                                       3 + 1 = 4

                                                                       That is true

-------> In the second equation, we would have 2(3) - 2(1/2) = 5

                                                                                6 - 1 = 5

                                                                          That is true

Our answer is found and checked.

(x, y) = (3, 1/2)

Answer:

angles b and c should be 153° each.

Step-by-step explanation:

We know the smaller angle is 27°. The other small angle, vertical to the 27° angle is also 27° because they are vertical angles. Along the lines, two angles should form 180°. So 180-27=153°. All together the angles should be 360°. Check your answer by doing 153+153+27+27=360. therefore the missing angles are both 153°

Answer: Maybe x = -5

Step-by-step explanation: Your equation isn't making complete sense to me. But since it sounds like x+5 is in the denominator, if I had to guess, I'd say when x = -5. This is when the denominator equals 0. Since we can't divide by 0, it's an asymptote.

 Rotation clockwise or counter clock wise with 180°

Step-by-step explanation:

Explanation:-

A triangle has coordinates at X(3,7),Y(6,7) and Z(4,2)

The Rule ( x, y)→ ( - x, -y)

This rule is given triangle is reflection  about origin or Rotation clockwise or counter clock wise with 180°

X( 3,7) → X¹ ( -3,-7)

Y(6,7) → Y¹ (-6,-7)

Z(4,2) → Z¹( -4 ,-2)

Answer:

45

Step-by-step explanation:

The required simplified value of the given expression a + b is given as 45.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,

According to the question,
3(-2m + 5)-6(-4m-2) = am + b

-6m + 15 +24m + 12 = am + b

18m + 27 = am + b

From the comparison,
a = 18 and b = 27

Now,
a + b = 18 + 27
        = 45

Thus, the required simplified value of the given expression a + b is given as 45.

Answer:24-12=12

Step-by-step explanation:

Answer:

6:10pm

Step-by-step explanation:

At 6:00 the hands are 180° apart.

The hour hand moves 1/12 of circle per hour = 30° per hour = 0.5° per minute.

The minute hand moves 1/60 of the circle per minute = 6° per minute

Angle between the hands decreases by 6-0.5 = 5.5° per minute.

180 - 5.5t = 125

t = 125/5.5 = 10 minutes

The hands are 125° apart at t minutes after 6:00, or 6:10.

Answer:

Marie ran at a faster rate. It takes 27 minutes for Lisa to run 15 laps while it takes Marie 26.25 minutes to run 15 laps.

Step-by-step explanation:

18 ÷ 10 = 1.8 (Lisa's rate)

14 ÷ 8 = 1.75 (Marie's rate)

1.8 x 15 = 27 minutes (How long it takes for Lisa to run 15 laps)

1.75 x 15 = 26.25 (How long it takes for Marie to run 15 laps)
