Answer:

£121

Step-by-step explanation:

5/12 of the total coins = 5/12 x 96 = 40   ⇒   40 coins are £2 coins

26 of the coins are £1 coins

Number of 50p coins = 96 - 40 - 26 = 30  ⇒  30 of the coins are 50p coins

Total money collected = 40 x £2 + 26 x £1 + 30 x £0.50 = £121

(rememberinf to convert 50p into £s)

How is the process of isolating a variable in these literal equations similar to solving a one-step equation? How is it differen
Phantasy [73]

Answer:

It is similar in that you have to move everything to one side and get rid of coefficients on the variable.

It is different in that you aren't solving for the actual numerical value of the variable and are just solving in terms of other variables.

Step-by-step explanation:

One step equations and literal equations both are similar because you have to move everything to the other side to isolate the variable, and also divide or multiply to get rid of any coefficients on the variable to solve it.

However, they are different because one-step equations actually need you to solve for the numerical value of the variable. On the other hand, literal equations aren't solved completely and are not numerical answers, it is just the variable solved in terms of other variables.

A friend rewrite the expression 5(x+2) as 5x+2. Write few sentances to your friend explaining the error. Then rewrite the expres
n200080 [17]
5(x+2) turns into 5x+10 where 5x+2 is already in its simplified form so to write it as 5x+2 instead would make you get the wrong answer.

Find three consecutive even integers such that the sum of the first, twice the second, three times the third is -76. What is the
ss7ja [257]

Answer:

The numbers are -14,-13 and -12

Step-by-step explanation:

<u><em>The correct question is </em></u>

Find three consecutive integers such that the sum of the first, twice the second and three times the third is -76. What is the number?

Let

x ----> the first consecutive integer

x+1 ---> the second consecutive integer

x+2 ---> the third consecutive integer

we have that

x+2(x+1)+3(x+2)=-76

solve for x

apply distributive property

x+2x+2+3x+6=-76

Combine like terms

6x+8=-76

subtract 8 both sides

6x=-76-8

6x=-84

Divide by 6 both sides

x=-14

so

x+1=-14+1=-13

x+2=-14+2=-12

therefore

The numbers are -14,-13 and -12
