What does that equal

son4ous [18]

Answer:

$3-\sqrt{10}$

Step-by-step explanation:

We are given an expression and are asked to find what it equals. We can see that the two square roots are being multiplied, therefore they follow the same standard as any multiplication problem, do as followed :

$\sqrt{5} *\sqrt{2}$

$\sqrt{10}$

Since a square root and constant number are different terms, we cannot combine them together, therefore leave as is :

$3-\sqrt{10}$

A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 70 p

nikklg [1K]

X = large boxes and y = small boxes

x + y = 70.....x = 70 - y
60x + 65y = 4300

60(70 - y) + 65y = 4300
4200 - 60y + 65y = 4300
5y = 4300 - 4200
5y = 100
y = 100/5
y = 20 <=== the small boxes weigh 20 lbs

x + y = 70
x + 20 = 70
x = 70 - 20
x = 50 <== and the large boxes weigh 50 lbs
