Answer:

PQ = 16.04cm

Step-by-step explanation:

θ = 76°

QR = 4cm

PQ = ?

Since it's a right angle triangle,

QR = adjacent

PQ = opposite

Tanθ = opposite/adjacent

Tan76 = pq / 4

PQ = 4tan76

PQ = 4 * 4.010

PQ = 16.04cm

kaheart [24]

6 cups of flour is needed for a big batch of cookies that uses 9 cups of oatmeal

Step-by-step explanation:

For 3 cups of oatmeal 2 cups of flour is required.

We need to find how much flour is needed for 9 cups of oatmeal.

Solving by using Unitary Method

3 cups of oatmeal require flour = 2 cups

1 cup of oatmeal require flour = \frac{2}{3}

9 cups of oatmeal require flour = \frac{2}{3}*9\\

                                                   = 6

So,  6 cups of flour is needed for a big batch of cookies that uses 9 cups of oatmeal

Solve this equation.<br> 5x-2y=3<br> y=2x
insens350 [35]

Answer:

3

Step-by-step explanation:

5x-2y=3  when: y=2x

1. Plug in the y-value (y=2x) into the equation (5x-2y=3). The equation should then look like 5x-2(2x)=3

2. Simplify:

5x-2(2x)=3

5x-4x=3

1x=3

x=3

Check:

5x-2(2x)=3 (plug in the x-value you solved for: 3)

5(3)-2×2(3)=3

15-2×6=3

15-12=3

3=3

Hope this helped !

Cheers, Z
