Answer:
The answer could be either 10 or -7
Step-by-step explanation:
(w-3)(w)=70
w^2 -3w=70
w^2 -3w-70=0
(w-10)(w+7)=0
w=10 or -7
Answer:
multiple choice is worth 2
short response is worth 4
Step-by-step explanation:
23x + 10y = 86
28x + 5y = 76
solve by elimination
multiply the top by -1 and the bottom by 2
-23x + -10y = -86
56x + 10y = 152
add them
33x = 66
x = 2
with x = 2 plug x into one of the equations
23x + 10y = 86
23(2) + 10y = 86
46 + 10y = 86
10y = 40
y = 4
x = 2 and y = 4 so
multiple choice is worth 2
short response is worth 4
Answer:
g=56
Step-by-step explanation:
In similar shapes, corresponding sides are always in the same ratio.
For example,
if the sides in triangle 1 were a and b, and triangle 2 had side lengths c and d, c and a had the same ratios, and b and d had the same ratios
and triangle 1 was similar to triangle 2, the ratio between the sides of the triangles would be
a/c, which is also equal to b/d
What that means is that in this situation, 8/5=g/35.
8/5=g/35
Cross multiply.
(8)*(35)=g*(5)
280=5g
g=56
Answer: 0.4332
Step-by-step explanation:
PEMDAS
(27^-30) first which is 1.14 I rounded up to the nearest hundredth place and i got my answer 1.14. the secondly you do 2/3 to the power of 1.14 which is 0.4332
Answer: yes
Step-by-step explanation: 5 is the product of 9 - 4, so if you multiply 5 x 10 which is 50, that will be how many more miles Greg bike than swam in 10 weeks. 50 miles
