muminat3 years ago
8 0

Step-by-step explanation:

u should:

7t = t + 48 » 7t - t = 48 » 6t = 48 » t = 8

and another one is:

2u + t + 13 = 10t + u - 44» 2u + 8 + 13 = 80 + u - 44»

» 2u + 21 = u + 36 » 2u - u = 36 - 21 » u = 15

Best way to convert measurements in the standard measurement system is to use the phrase "King Henry Died By Drinking Chocalote Milk"

K- Kilo
H- Hecto
D- Deca
B- Base (meter, liter, gram)
D- Deci
C- Centi
M- Milli

If you go up from the B, you move the decimal left, if you go down from the B, you move the decimal that many times to the right.

The picture will probably help explain better.

3) 10,640 g
5) idk which it needs to be converted to
7) 3,700 mg

Leah has a 20% off coupon for a sports store. There is a tennis racket that is available at a discount of 10%. The store applies
Art [367]

Answer:the orginal price of the tennis racket is $47

Step-by-step explanation:

Let x represent the original price of the tennis racket at the sports store.

Leah has a 20% off coupon for the sports store. The tennis racket is available at a discount of 10%.

The store applies the coupon after the 10% is taken. The value of the discount on the original price of the tennis racket would be

10/100 × x = 0.1 × x = $0.1x

The discounted price of the racket would be

x - 0.1x = 0.9x

The value of the coupon would be

20/100 × 0.9x = 0.2 × 0.9x = 0.18x

The selling price after the coupon was applied would be

0.9x - 0.18x = 0.72x

She buys the racket for $34. This means that

0.72x = 34

x = 34/0.72 = $47

Six time a number is greater than -60. What are the possible values for the number?
baherus [9]

Answer:

Suppose that x is some number so 6 times a number is 6*x. 20 more than that number is 20 + x. If you put it together the inequality would be 6x > 20 + x. Subtracting x from both sides would result in 5x > 20. Dividing by 5 gives you x > 4 which is the final answer. So the possible values of that number is anything greater than 4.
