If you're trying to solve for y,
5y-4=7
bring over the -4
5y=11
5y/5 = y
11/5 = 2.2
y= 2.2

a class has 20 trays of paint each trays has 6 colors 1 of the color is red what fraction of the colors in the 20 trays is red

Molodets [167]

Answer: it is 1/6

You can solve by saying, 1 out of 6 in each tray is red, so my fraction should be 1/6.

It doesn't matter the amount of trays because the pattern is always the same.

But if you want to check it out you can do it in this way.

You know there is 1 red color per tray, if there are 20 then you'd have 20 of them, in each tray there are 6 colors so the total is 120.

Now you solve it if there are 20 red colors out of 120 them the answer is 20/120, thus you get 1/6

The base of a triangle exceeds the height by 7 centimeters . If the area is 114 square centimeters, find the length of the base

Ganezh [65]

Answer:

base length = 19 cm , height = 12 cm

Step-by-step explanation:

Area formula : A = (1/2)*b*h

b = h + 7 cm

A = 114 sq. cm

114 = (1/2) * (h + 7) *h

228 = hh + 7h

hh + 7h - 228 = 0

h = -7/2 + root( 49 - 4*(-228)) /2

h = -7/2 + 31/2

h = 24/2 = 12 cm

base = 12 cm + 7 cm = 19 cm

BRAINLIEST AND 100 POINTS BRAINLIEST TO THE FIRST CORRECT ANSWER!

Nady [450]

Answer:

5 5/7

Step-by-step explanation:

-4*6/7*-5/3

We can multiply the numerators

-4 * 6*-5 = 120

We can multiply the denominators

7*3 =21

Put the numerator over the denominator

120/21

The top and bottom are both divisible by 3

120/3 = 40

21/3 =7

The new improper fraction is 40 /7

Changing from an improper fraction to a mixed number

7 goes into 40 5 times with 5 left over

5 5/7
