-10 = y/11 - 13<br><br> solve for y
Flauer [41]

Answer:

10=y/11-13

We move all terms to the left:

-10-(y/11-13)=0

-y/11+13-10=0

We multiply all the terms by the denominator

-y+13*11-10*11=0

We add all the numbers together, and all the variables

-1y+33=0

We move all terms containing y to the left, all other terms to the right

-y=-33

y=-33/-1

y=+33

How do you do this problem?
erastovalidia [21]

Step-by-step explanation:

∫₀² x f(x²) dx

If u = x², then du = 2x dx, and ½ du = x dx.

When x = 0, u = 0.  When x = 2, u = 4.

∫₀⁴ ½ f(u) du

½ (16)

Sarah walks to school, 1.5 miles in 30 minutes. what is the snswer to this
nevsk [136]

Answer: 3 mi/h

Step-by-step explanation:

Here we have to find the speed V at which Sarah walks to school, knowing the distance d she has walked and the time t she expends.

So, in this case we can use the following equation:

V=\frac{d}{t}

Where:

d=1.5 mi

t=30 min \frac{1 h}{60 min}=0.5 h

Solving:

V=\frac{1.5 mi}{0.5 h}

V=3 mi/h This is Sarah's speed

Geometry solve for x
Stels [109]

Answer:

x = 74 degrees

Step-by-step explanation:

If we assume that this triangle is isosceles, then the sum of the two angles at the bottom is (180 - 32) degrees, or 148 degrees.  The angle x is half that, i. e., x = 74 degrees
