Answer:

ANSWER: 18 blue ribbons and 12 red ribbons

Step-by-step explanation:

for every 3 blue ribbons there is 2 red ones

so if we add 3+2 that is 5 then divide 30 by 5 would be 6 and then separate back into basic numbers so there would be 6 threes and six twos so 18 and 12.

Answers

Answer:

x = 19

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

h is the perpendicular height and b₁ , b₂ the parallel bases

Here A = 180.5 , h = x , b₁ = 13 and b₂ = 6 , then

[tex]\frac{1}{2}[/tex] x (13 + 6) = 180.5 ( multiply both sides by 2 to clear the fraction )

x × 19 = 361 ( divide both sides by 19 )

x = 19

Two angles M and R are vertical angles. Angle M is (12x+8) degrees and Angle R is (-5x+76) degrees. What is the value of x?

Answers

X=4
We know this because of the given information that both angels are vertical angles indicating that they’re the same measurement so we can make our equation 12x+8=-5x+76 and first add 5x to both sides in order to cancel out -5x on the right side now from this we have 17x+8=76 and subtract 8 from both sides to cancel positive 8 in the left side and now 17x=68 divide both sides by 17 and get x=4

Every​ hour, 70 people enter an office​ building, and 42 people leave. After how many hours will there be more than people in 140 the​ building? Solve the inequality 70n-42n>140

Answers

Answer:

After 6 hours there will be more than 140 people, but after 5 hours there will be exactly 140 people. I don't know if this question is meant to trick you or not.

Step-by-step explanation:

To find out, 70 - 42 = 28, 140/28 = 5 after 5 hours

70(5) - 42(5) = 350 - 210 = 140

But the question asks when will there be MORE than 140 people, after 5 hours there will be 140 people, and 140 > 140 is not true, so its after 6 hours
