Kristin spent $120 on shirts. Dress shirts cost $40 and t-shirts cost $8. If she bought a total of 7 shirts, then how many of ea

FinnZ [79.3K]

Answer:

The correct answer is: She bought 2 dress shirts and 5 t-shirts

Step-by-step explanation:

Let's marked dress shirts with x and t-shirts with y.

Now we will make equations to solve this problem:

x + y = 7 => y = 7 - x

40 x + 8 y = 120

When we replace y = (7 - x) in the previous equation we get:

40 x + 8 (7 -x) = 120 40 x + 56 - 8 x = 120 => 32 x = 120 - 56 =>

32 x = 64 => x = 64/32 = 2 => x = 2

y = 7 - x = 7 - 2 = 5 => y = 5

x = 2 dress shirts

y = 5 t-shirts

Three consecutive integers add up to 51. What are these integers

kaheart [24]

Let the three consecutive integers be x, x+1 and x+2.

According to the question, x+x+1+x+2=51

=>3x+3=51

=>3x+3-3=51-3

=>3x=48

=>x=16

Hence, first integer = 16,

second integer = 16 + 1 = 17 and

third integer = 16 + 2 = 18.

Elijah and his sister went to the movies. They had 34 altogether and spent 9.50 per ticket. Elijah and his sister bought the sam

Zarrin [17]

Answer:

The Inequality to find the amount of money they spent on snack is $2(9.5+x)\leq 34$

Maximum amount each person can spent on snack is 7.5.

Step-by-step explanation:

Given:

Total Money they had = 34

Cost of each ticket = 9.5

Number of persons = 2

Let the cost of snacks bought by each be x.

We need to write inequality and solve for the amount each persons spent on snacks.

Solution:

Now we can say that;

Number of persons multiplied by sum of Cost of each ticket and Cost of each person spent on snack should be less than or equal to Total money they had.

framing in equation form we get;

$2(9.5+x)\leq 34$

Hence the Inequality to find the amount of money they spent on snack is $2(9.5+x)\leq 34$

On Solving the above Inequality we get;

$2(9.5+x)\leq 34\\\\19+2x\leq 34$

Now By Using Subtracting property of Inequality we will subtract both side by 19 we get;

$19+2x-19\leq 34-19\\\\2x\leq 15$

No By Division Property of Inequality we will divide both side by 2 we get;

$\frac{2x}{2}\leq \frac{15}{2}\\\\x\leq 7.5$

Hence maximum amount each person can spent on snack is 7.5.

Interpreting the solution we get;

Now Cost of 1 ticket = $9.5

Number of person = 2

So total cost of ticket = $19

Total money they have = $34

Money left = Total money - total cost of ticket =$34 -$19 = $15

Amount of money left = $15

Now each buys the same snack.

So maximum amount of money each can spent on snack = $7.5

Factor each completely. <br><br>10a² - 9a + 2 <br><br>

Sophie [7]

Answer:

a= $\frac{2}{5}$ or $\frac{1}{2}$

Step-by-step explanation:

Equate the equation to zero

$10a^{2}$ -9a+2=0

$10a^{2}$ -5a-4a+2=0

5a(2a-1)-2(2a-1)=0

Write out the factors

(5a-2)(2a-1)=0

Then equate each factor to zero

5a-2=0 OR 2a-1=0

5a=2 OR 2a=1

a= $\frac{2}{5}$ OR a= $\frac{1}{2}$

a= $\frac{2}{5}$ or $\frac{1}{2}$
