1+2+3+4+5+6+7+8+9+10+11+12=78
The answer is 78
Three times seven is twenty one and eight times none is eighty one so the answer is 21/81 or 7/24
Answer:
To round to three significant figures, look at the fourth significant figure. It's a 5 , so round up.
To round to four significant figures, look at the fifth significant figure. It's a 1 , so round down.
To round to two significant figures, look at the third significant figure. It's an 8 , so round up.
Answer:
-37
Step-by-step explanation:
1) to find the equation of the given line (its slop-interception form is y=mx+i, where m - slop, i - interception):
a) y=2x+i, where m=2;
b) it is possible to calculate the value of 'i' after the substitution the point (5;-3) into the equation y=2x+i:
-3=2*5+i; ⇒ i= -13;
c) the equation of the given line is y=2x-13.
2) to calculate the value of 'R':
if to substitute the point (-12;R) into the equation y=2x-13, then
R=2*(-12)-13; ⇒ R= -37.
Answer:
B
Step-by-step explanation:
Given
+ 5 = 12 ( subtract 5 from both sides )
= 7 ( square both sides )
x - 6 = 49 ( add 6 to both sides )
x = 55
