C - 12 = -14<br> and<br> 7 + x = -1<br> plz help thank you

Misha Larkins [42]

Answer: x= -2, c= -8

Step-by-step explanation: To solve the first equation, move the 12 over to the right side. To do this, do the oposite operation. So add 12 on both sides. The 12 on the left side cancels out, and you are left with x= -14+12. X=-2. Do the same thing for the next equation. Subtract 7 from the left side and the right side. C= -1-7. C= -8

IrinaVladis [17]

Answer:

$345$

Step-by-step explanation:

$7-\left(-19\right)-18+\left(-19\right)+187-\left(-19\right)-18+\left(-19\right)+187$

$7+19-18+\left(-19\right)+187-\left(-19\right)-18+\left(-19\right)+187$

$26-18+\left(-19\right)+187-\left(-19\right)-18+\left(-19\right)+187$

$8+\left(-19\right)+187-\left(-19\right)-18+\left(-19\right)+187$

$8-19+187-\left(-19\right)-18+\left(-19\right)+187$

$-11+187-\left(-19\right)-18+\left(-19\right)+187$

$176-\left(-19\right)-18+\left(-19\right)+187$

$195-18+\left(-19\right)+187$

$177+\left(-19\right)+187$

$177-19+187$

$158+187$

$=345$

A lemonade stand sells drinks in two sizes, small and medium. In the span of 1 hour, the stand sold 72 drinks. The ratio of smal

Mashutka [201]

Answer:

The total amount of money received at the lemonade stand was $49.50

Step-by-step explanation:

Let

x ---> the number of small drinks sold

y ---> the number of medium drinks sold

we know that

The stand sold 72 drinks

so

$x+y=72$ ----> equation A

The ratio of small drinks to medium drinks sold was 5:3

$\frac{x}{y}=\frac{5}{3}$

$x=\frac{5}{3}y$ ----> equation B

substitute equation B in equation A

$\frac{5}{3}y+y=72$

$\frac{8}{3}y=72\\\\y=72(3)/8\\\\y=27$

Find the value of x

$x=\frac{5}{3}(27)=45$

Find out the total amount of money received at the lemonade stand

$0.50(45)+1.00(27)=\$49.50$
