Answer:
D) 6.003 ÷ 12
Step-by-step explanation:
All of the quotients differ from 0.5 by at least one order of magnitude except ...
6.003/12 = 0.50025
__
The others are ...
A: 0.301/60 = 0.0050166... (repeating)
B: 0.051/10 = 0.0051
C: 2.499/49 = 0.051
Answer:
(1/2,4)
Step-by-step explanation:
First, determine y in first equation: 2x+y=5 or y=5-2x
replace value of y determined in first equation (5-2x) into 2nd equation
4x-3(5-2x)=-10
4x-15+6x=10
10x=5
x=1/2
put value of x into either equation to solve for y so
2(1/2)+y=5
1+y=5
y=4
answer: x=1/2, y=4
check answer by substituting x and y into either equation:
4x-3y=-10
4(1/2)-3(4)=-10
2-12=-10
-10=-10
or
2x+y=5
2(1/2)+4=5
1+4=5
5=5
Answer:
144
Step-by-step explanation:
6^2 = 6x6 = 36
36 x 4 = 144
Answer:
23.7 -2.5 X 8 = 23.7 - 20
= 3.7
Answer:
x = 3.51
Step-by-step explanation:
Since, formula to determine the area f a triangle is,
Area = 
8 = 
16 = x(3x - 7) + 1(3x - 7)
16 = 3x² - 7x + 3x - 7
16 = 3x² - 4x - 7
0 = 3x² - 4x - 23
3x²- 4x - 23 = 0
By quadratic formula,
x = 
x = 
x = 
x = 
x = 3.51, -2.18
But the length of sides can't be negative.
Therefore, x = 3.51 will be the answer.
