Answer:
42cm
Step-by-step explanation:
so if for every 11 feet you get 2 inches then for every 5.5 feet you get 1 cm. so if you break up the total number of feet into 220+16 it will be easier to solve. because 11*20=220ft so then you know you can do 2*20=40cm. now you can simplify 16 into 11+5 and get 11*1=11ft and 2*1=2cm. now youre left with 5ft and 5.5ft is 1 cm so you know that you have just under 1 cm. now add them all up 220ft+11ft+5ft=236ft and 40cm+2cm=42 cm
12(3x+4)-5(2x-6)=6x-22
36x + 48 - 10x + 30 = 6x - 22
26x + 48 + 30 = 6x - 22
26x + 70 = 6x - 22
20x + 70 = -22
20x = -92
x = -4.6
Answer:
19.1sq cm
Step-by-step explanation:
10+9=19 so after that, you have to add the decimals, .4+.6=.10. then to make it easier you can take off the zero on the end so it reads as 19.1 .
Hope this helps!☺
Given:
m∠A = 86°
Because the measure of angle B is 22 degrees more than three times the measure of angle C, therefore
m∠B = 3*m∠C + 22 (1)
The sum of the angles should be 180°, therefore
m∠A + m∠B + m∠C = 180 (2)
Note that m∠A = 86°
Substitute equation (1) for m∠B in equation (2) to obtain.
86 + (3*m∠C + 22) + m∠C = 180
86 + 3*m∠C + 22 + m∠C = 180
4*m∠C = 180 - 86 - 22 = 72
m∠C = 72/4 = 18°
Answer: m∠C = 18°
