Answer:
m<DBE =50°
m<ABD=150°
Step-by-step explanation:
Because of Straight Angles, All the angles will add up to 180 degrees
Let x be m<DBE
40+x+70+20=180
x+130=180
x=50
m<DBE will be 50 degrees
To find the m<ABD, we add m<FBA, m<FBE, m<DBE.
70+50+30=150
m<ABD = 150
Answer:
x=4
Step-by-step explanation:
First set the equation equal to 4:
-2x +12=4
Subtract 12 from both sides:
-2x +12=4
-12 -12
-2x=-8
Then divide each side by -2 to isolate the x:
-2x/-2=-8/-2
x=4
Answer:
Identifying and Writing Equivalent Rates
Ratios compare two quantities. A rate is a type of ratio that compares two quantities that have different units of measurement. The word “per” is often used to describe rates.
Rates can be written as fractions. The first quantity is the numerator and the second quantity is the denominator. Different rates that have the same value are equivalent rates. You can find an equivalent rate the same way you find equivalent ratios—divide or multiply the numerator and the denominator by the same number.
