10(23+7)=100ℓ+100ℓ What is the value of \large\ellℓell in the equation above?

Answers

Answer 1

Answer:

Answer:

ℓ = 1.5

Step-by-step explanation:

An equation 10(23+7)=100ℓ+100ℓ is given and we are asked to find the value of ℓ.

To solve the equation, we have to move all the values containing ℓ on one side and other values on other side of equality.

10(23+7)=100ℓ+100ℓ

Multiply 10 with 23 and 7 which gives

(10 * 23 ) + ( 10 * 7) = 200 ℓ

Solving the above equation,

230 + 70 = 200 ℓ

300 = 200 ℓ

=> ℓ = 300 / 200

=> ℓ = 3/2

=> ℓ = 1.5

the spring musical sold student tickets for $8 and adult tickets for $10. there were 130 tickets sold for a total of $1198. how many student tickets were sold?

Answers

x=number of student tickes
y=number of adult tickets

total cost=8x+10y=1198
x+y=130
multipy second eatuion by -10 and add to first

-10x-10y=-1300
8x+10y=1198 +
-2x+0y=-102

-2x=-102
divide both sides by -2
x=51

51 student tickets sold

Okay, so the equation can be written as:

where x is number of student tickets, and y is adult tickets

8x + 10y = 1198

x + y = 130

Lets solve for x,

x = 130-y

Put value of x in first equation:

8 (130-y) + 10y = 1198

1040 - 8y + 10y = 1198

1040 + 2y = 1198

2y = 158

y = 79

Since we have to find student tickets, we will write:

x + 79 = 130

x = 51

So 51 student tickets were sold.

Mags is 2 years older than vector . if mags is 34 years old how old is vector

Answers

Answer:

Vector is 32 years old.

Step-by-step explanation:

As it is given that Mags is 34 years old and he is 2 years older than Vector.

Since Mags is 2 years older than Vector, Vector's age is 2 year less than Mags.

therefore we subtract 2 years from the age of Mags.

= 34 - 2 = 32 years

So Vector is 32 years old.

Answer: it is

Since there are 5,280 feet in one mile and 3.3 feet in one meter, how many meters per second are equivalent to 60 miles per hour?a.) 26 $(2)/(3)$ meters per second
b.) 198 meters per second
c.) 266 $(2)/(3 (2)/(3) )$ meters per second
d.) 290 $(2)/(5)$
please explain.

Answers

Given:
1 mile = 5280 feet
1 meter = 3.3 feet

convert 60 miles per hour to meters per second

60 miles to meters

60 miles x 5280ft x 1meter = (60*5280m)/3.3 = 316800m/3.3
1 mile 3.3ft
= 96,000 meters

1 hour to seconds

1 hour x 60 minutes x 60 seconds = 1 * 60 * 60sec = 3600 seconds
1 hour 1 minute

unit rate: meters per second

96000 meters ÷ 3600 seconds = 26 2400/3600
simplify 26 2400/3600 ⇒ 26 2/3 meters per second

2400 ÷ 1200 = 2
3600 ÷ 1200 = 3
