Answer:
v =7
Step-by-step explanation:
Simplifying
v + -10 = -3
Reorder the terms:
-10 + v = -3
Solving
-10 + v = -3
Solving for variable 'v'.
Move all terms containing v to the left, all other terms to the right.
Add '10' to each side of the equation.
-10 + 10 + v = -3 + 10
Combine like terms: -10 + 10 = 0
0 + v = -3 + 10
v = -3 + 10
Combine like terms: -3 + 10 = 7
v = 7
Simplifying
v = 7
Answer:
The number of apples bought was 7 and the number of pears bought was 4
Step-by-step explanation:
<u><em>The correct question is</em></u>
Thanh bought 11 pieces of fruit and spent $5.60. If apples cost $0.60 each and pears cost $0.35 each, how many of each kind of fruit did he buy?
Let
x ---->the number of apples bought
y ----> the number of pears bought
we know that
Thanh bought 11 pieces of fruit
so
----> equation A
apples cost $0.60 each and pears cost $0.35 each and Thanh spent $5.60
so
----> equation B
Solve the system of equations by graphing
Remember that the solution is the intersection point both graphs
Using a graphing tool
The solution is the point (7,4)
see the attached figure
therefore
The number of apples bought was 7 and the number of pears bought was 4

Answer:
Step-by-step explanation:
The triangle is a right angle triangle. This is because one of its angles is 90 degrees.
Let us determine x
Taking 47 degrees as the reference angle,
x = adjacent side
11 = hypotenuse
Applying trigonometric ratio,
Cos # = adjacent side / hypotenuse
# = 47 degrees
Cos 47 = x/11
x = 11cos47
x = 11 × 0.6820
x = 7.502
Let us determine y
Taking 47 degrees as the reference angle,
y = opposite side
11 = hypotenuse
Applying trigonometric ratio,
Sin # = opposite side / hypotenuse
# = 47 degrees
Sin 47 = y/11
x = 11Sin47
x = 11 × 0.7314
x = 8.0454
