Answer:

x = 13.

So the 3 angles are a =  44, b = 47 and c = 89 degrees.

Step-by-step explanation:

If these are the angles  are the 3 angles of a triangle they sum to 180 degrees, so:

3x + 5 + 5x - 18 + 7x - 2 = 180

15x - 15 = 180

15x = 195

x = 195/15

x = 13.

There is 3/4 pound of cream in a containwr. Julian will use 3/8 pound of cream to make crème brûlée. What fraction of a pound of
Ksivusya [100]

Answer:

\frac{3}{8}\ pound of cream will remain in the container.

Step-by-step explanation:

Given:

Amount of cream in the container = \frac{3}{4}\ pound

Amount of cream used to make crème brûlée = \frac{3}{8}\ pound

We need to find the amount of cream remain in the container.

Solution:

Now we can say that;

the amount of cream remain in the container is equal to Amount of cream in the container minus Amount of cream used to make crème brûlée.

framing in equation form we get;

amount of cream remain in the container = \frac{3}{4}-\frac{3}{8}

Now we will make the denominator common using LCM we get;

amount of cream remain in the container = \frac{3\times2}{4\times2}-\frac{3\times1}{8\times1}= \frac{6}{8}-\frac{3}{8}

Now denominators are common so we will solve the numerators.

amount of cream remain in the container = \frac{6-3}{8}=\frac{3}{8}\ pound

Hence \frac{3}{8}\ pound of cream will remain in the container.

40 POINTS AND BRAINLIEST
ladessa [460]

Answer:

120

Step-by-step explanation:

As x goes from 1 to 2, y increases by 4 from 4 to 8

As x goes from 2 to 3, y increases by 4 from 8 to 12

We increase by 4 each time

The formula for an arithmetic sequence is

an = a1+d(n-1)

where a1 is the first term which is 4

d is the common difference or the number we add each time which is 4

n is the term we are looking for which is 30

a30 = 4 +4 (30-1)

a30 = 4+4(29)

       = 4+116

      = 120
