At a fundraiser, students sold chocolate bars with almonds and chocolate bars with walnuts. The number of chocolate bars with al
BabaBlast [244]

Answer:

Total number chocolate bars with almonds sold were approximately 66.34 and total number chocolate bars with walnuts sold were approximately 34.67.

Step-by-step explanation:

Let number chocolate bars with almonds be x

Also let number chocolate bars with walnuts be y

Given:

Number of chocolate bars with almonds that were sold one weekend was 3 less than 2 times the number of chocolate bars with walnuts.

Framing the above sentence in equation form we get;

x=2y -3

Also given:

The number of chocolate bars with walnuts plus 4 times the number of chocolate bars with almonds was 300.

Framing the above sentence in equation form we get;

4x+y=300

Now Substituting the value of x in above equation we get;

4x+y=300\\4(2y-3)+y=300\\8y-12+y=300\\9y=300+12\\9y=312\\\\y=\frac{312}{9} \approx 34.67

Now we will substitute the value of y in equation x=2y -3 we get;

x=2y-3 = 2\times34.67 -3 = 69.34-3\approx66.34

Hence, Total number chocolate bars with almonds sold were approximately 66.34 and total number chocolate bars with walnuts sold were approximately 34.67.

Marina CMI [18]

Answer: The greatest number of pages Kenji can decorate = 3

Step-by-step explanation:

Given: Total heart stickers = 15

Total star stickers =12

If all the papers identical, with the same combination of heart and star stickers and no stickers left over.

Then the greatest number of pages Kenji can decorate = GCD(15,12)  [GCD=greatest common divisor]

Since 15 = 3 x 5

12=2 x 2 x 3

GCD(15,12) =3

Hence, the greatest number of pages Kenji can decorate = 3

When solving negative one over eight (x + 35) = −7, what is the correct sequence of operations?
Fantom [35]
The answer is <span>Multiply each side by −8, subtract 35 from each side

</span>- \frac{1}{8}(x+35)=-7
<span>
Multiply each side by -8:
</span>(-8)(- \frac{1}{8})(x+35)=(-8)(-7) \\  \\ &#10;1(x + 35) = 56 \\ &#10;x + 35 = 56
<span>
Subtract 35 from each side:
</span>x + 35 -35 = 56-35 \\  \\ &#10;x + 0 =21 \\  \\ &#10;x = 21<span>
</span>
