0.25 (y-4)+0.07=0.22y-0.05 (60)

1 answer:

5 0

First, let's use distributive property and expand this equation:

0.25 (y-4)+0.07=0.22y-0.05 (60)
0.25y - 1 + 0.07= 0.22y - 3

Now, isolate the values of y and solve!

0.25y - 1 + 0.07= 0.22y - 3
0.25y - 0.22y = 1 - 0.07 - 3
0.03y = -2.07
y = -69

Hope this helps!

Step-by-step explanation:

Step 1: Define

$\displaystyle N = S(P - V) - F$

Step 2: Solve for S

Rearrange.

[Addition Property of Equality] Add F on both sides: $\displaystyle N + F = S(P - V)$
[Division Property of Equality] Isolate S: $\displaystyle \frac{N + F}{P - V} = S$
Rewrite: $\displaystyle S = \frac{N + F}{P - V}$

Lauren has finished 25% of the 120 push ups she needs to do for softball

Ilya [14]

Answer:

30 pushups

Step-by-step explanation:

25/100 = x/120

so, 120x25 = 100x

3000 = 100x

3000/100= x

x = 30

so, Lauren has completed 30 push-ups.

In the given figure, mBC =118°, mBE=76°, and m

levacccp [35]

Answer:

Correct option: A

Step-by-step explanation:

The angle BDC inscribe the arc mBC, so we have that:

mBDC = (1/2) * mBC

mBDC = (1/2) * 118 = 59°

From the secants relation in a circle, we have that:

mA = (1/2) * (mBC - mDE)

35 = (1/2) * (118 - mDE)

70 = 118 - mDE

mDE = 48°

The sum of the arcs is 360°, so we have:

mBC + mCD + mDE + mBE = 360

118 + mCD + 48 + 76 = 360

mCD = 360 - 118 - 48 - 76 = 118°

The angle mCBD inscribes the arc mCD, so we have:

mCBD = (1/2) * mCD = (1/2) * 118 = 59°

The angles mCBD and mBDC are equal, so the triangle is isosceles.

Correct option: A

Mixed number fraction 7and1/5+3and2/5

PtichkaEL [24]

Answer:

53/5 = 10 3/5

Step-by-step explanation:

convert both to fraction

7x5 + 1 = 36

3x5 + 2 = 17

36 + 17 = 53

actually you could have just added

7 + 3 = 10

1 + 2 = 3 for the fraction
