On a bike trip across the United States Rodney notes that he covers about 190 miles every 4 days. If he continues at this rate use a ratio table to determine about how many miles he could bike in 6 days

Answers

4-190 190 divided by 4 is 47.5, so Rodney travels 47.5 miles per day. if Rodney travel 190 miles in 4 days, at 47.5 miles to 190 to find out how far he would travel in 5 days. 190+47.5= 237.5 ---------------------------- day #4-190 miles day #5-237.5 miles day #6-285 miles

Answer:

7) 40

8) 23

9) 63

Step-by-step explanation:

180 degrees in a triangle. Add the 2 degrees they give you, and then subtract that from 180 to find the missing angle.

82 + 58 = 140 180 - 140 = 40

115 + 42 = 157 180 - 157 = 23

27 + 90 = 117 180 - 117 = 63

Hope this helps.

Answer:

7=40, 8=23, and 9=63

Step-by-step explanation:

The key info to solve is that in a triangle there are 180 degrees

7) we add 82 and 58 and then subtract the total from 180 to find x

=82 + 58 = 140, and 180 - 140 = 40, so 40=x

We do the same for the rest

115 + 42 = 157, and 180 - 157 = 23, so 23=x

Wait whats that square in the triangle? It represents 90 degrees, a right angle!

so, 27 + 90(right angle) = 117, and 180 - 117 = 63, so 63=x

Answers

Infinitely many solutions.I will try to solve your system of equations.3x+y=9;3x=−y+9Step: Solve3x+y=9for y:3x+y+−3x=9+−3x(Add -3x to both sides)y=−3x+9Step: Substitute−3x+9foryin3x=−y+9:3x=−y+93x=−(−3x+9)+93x=3x(Simplify both sides of the equation)3x+−3x=3x+−3x(Add -3x to both sides)

so ur answer is
Infinitely many solutions.

In triangle LMN, the measure of m_L =75°and m_M is one-half m_N. what is m_M?

Answers

Let m(<N) be x;
We have m(<M) = 1.5x;
We solve the equation: 75 + x + 1.5x = 180;
75 + 2.5x = 180;
2.5x = 105;
x = 105 ÷ 2.5;
x = 42;
Finally, m(<M) = 63 degrees;
