Answer:

p>31/60

−3−(−3p+7)>6p+21(1−3p)

Step 1: Simplify both sides of the inequality.

3p−10>−57p+21

Step 2: Add 57p to both sides.

3p−10+57p>−57p+21+57p

60p−10>21

Step 3: Add 10 to both sides.

60p−10+10>21+10

60p>31

Step 4: Divide both sides by 60.

60p

find two consecutive integers such that ten more than twice the smaller is seven less than three times the larger

Radda [10]

This is how I would work it out:

1st no. = x+1 2x+10=3(x+1)-7
2nd no. = x 2x+10=3x-4
x=14

1st no. is 15; 2nd no. is 14

To check: 28+10=38; three times the larger is 45; and 38 is 7 less than 45.

7. Write the following proportion: 8 is to 64 as 2 is to X

Paul [167]

2 is to 4 because 64/8 is 8. 4/2 is 2. 2 x 2 is in proportion to 8 x 8

Moscow, the capital city of Russia, is at 37.62 degrees longitude and 55.75 degrees latitude. Brasilia, the capital city of Braz

notsponge [240]

The distance between two positions with longitudes A and B is given by ||A| - |B|| if the two positions are at the same side of the meridian (0 degrees longitude) and |A| + |B| if both positions are at different sides of the meridian.

Given that <span>Moscow is at 37.62 degrees longitude and Brasilia is at -47.87 degrees longitude, thus the two cities are at different sides of the meridian.

Therefore, the distance </span><span>(in degrees) between the longitude lines of Moscow and Brasilia</span> is |37.62| + |-47.87| = 37.62 + 47.87 = 85.49

the equation 7x - 3y = 42 relates to x and y. find three pairs of points (x,y) that make the equation true.

Sloan [31]

If it doesn't matter whether the points are integers or not you can just pick a number for either y or x and solve for the other variable. For example, if you pick 3 to be your x, plug it in and then solve for y. Start out with: $7x-3y=42$ Plug in 3 for x: $7(3)-3y=42$ . Then, $21-3y=42$ . Subtract 21 from both sides and then divide by -3 on both sides. You end up with y=-7 so one of your points is (3, -7)

Angela is following this recipe to make biscuits.

Answer : The amount of margarine needed is 1 kg.

Step-by-step explanation :

First we have to convert volume of syrup from mL to L.

Conversion used:

1 L = 1000 mL

or, 1 mL = 0.001 L

So, 225 mL = 0.225 L

Now we have to calculate the amount of margarine needed.

As, 0.225 L of syrup needed 150 g of margarine

So, 1.8 L of syrup needed $\frac{1.5L}{0.225L}\times 150 g=1000g$ of margarine

Amount of margarine needed = 1000 g = 1 kg (1 kg = 1000 g)

Therefore, the amount of margarine needed is 1 kg.
