Answer:

x=-1 so the answer is -39

Step-by-step explanation:

(28x-6)29 5E2=49 Start with the given equation.

x-6=22 22 2B-sqrt 2849 29 Take the square root of both sides.

x-6=sqrt 2849%29 or x-6=-sqrt 2849%29 Break up the "plus/minus" to form two equations.

x-6=7 or x-6=-7 Take the square root of 49 to get 7.

x=6%2B7 or x=6-7 Add 6 to both sides.

x=13 or x=-1 Combine like terms.

She needs 8 daisies.

1 arrangement = 10 flowers = 2/10 are daisies.
4 * 10 = 40 flowers
2/10 * 40 = 80 / 10 = 8 daisies.

4 arrangements = 40 flowers = 8/40 are daisies

Proportionality: where a/b = c/d

a = 2 daisies
b =10 flowers
c = 8 daisies
d = 40 flowers

We will know if the proportions are correct because the cross products will be equal.

ad = bc
2*40 = 10*8
80 = 80

Juan is 1 1/4 feet shorter than Maria. Maria is 1/3 foot taller than Luis. If Luis is 62 inches tall, how tall are Maria and jua

Nataliya [291]

Answer:

Maria is 66" tall, Juan is 51" tall

Step-by-step explanation:

There are 12 inches to a foot.

Luis is 62" tall

Maria is 1/3 of a foot taller than Luis, 1/3 of 12 is 4, (multiply 12 by 1/3)

So Maria is 4 inches taller than Luis, making her 66" tall

Juan is 1 1/4 feet shorter than Maria, that's one foot and 1/4 of a foot shorter, 1/4 of 12 is 3 (multiply 12 by 1/4)
