Answer:
His test IS a solution.
Step-by-step explanation:
Both LHS and RHS are equal so it is a solution.
Sum of geometric sequence
for the sum where the initial value is a₁ and the common ratio is r and the term is n

common ratio is -3
-5 times -3 is 15, -15 times -3=-45 etc
first term is -5
and we want the 8th term





the sum is 8200
Answer:Yes she has enough
Step-by-step explanation:
Total ounces=11
1st recipe=6 ounces
2nd recipe=1/4 ounces
1 pound =16 ounces
= 1/4 pounds × 16 ounces/1 pound
= 4 ounces
First recipe + Second recipe
= 6 ounces + 4 ounces
= 10 ounces.
10 ounces of walnuts and Marni has 11
If 3mile=28 min
x mile=42 min
cross multiply
x=3/28
therefore if 3/28=1 min
then x mile= 42 min
cross multiply
42 x 3/28 =21 x 3/14
=3 x 3/1
=9
The answer is 9 miles
Answer:
The coordinates of H′ are (-2,0).
Step-by-step explanation:
It is given that square EFGH stretches vertically by a factor of 2.5 with respect to the x-axis to create rectangle E′F′G′H′.
If a figure stretches vertically by a factor of 2.5 with respect to the x-axis, then the x-coordinates remains same and the points which lie on the axis are also remains the same after stretch.
It is given that the coordinates of H are (-2,0). This point lie on the x-axis, therefore it will remains the same after stretch.
Therefore the coordinates of H′ are (-2,0).
