Answer:
see the explaination
Step-by-step explanation:
let x be 3:3:5
3x:3x:5x
3x is splice cookies
3x is snickerdoodle cookies
5x is no bake cookies
where 5x is equal to 45
x is equal to 45÷5=9
so x is equal to 9
now,
3x = 3×9=27
3x = 3×9=27
5x = 45 (given)
now add all, total cookies =27+27+45
=99 cookies
so there are total 99 cookies in a cookie mix
Answer:
No, it's not equivalent
Step-by-step explanation:
Try and solve the one with the bracket first. Expand 8(15-r) : 8x15 and 8x-r = 120 - 8r
Therefore, the equation can now be written as:
6r-r + 120-8r + 23-6
Rearrange the like terms together and solve the equation:
6r-r-8r + 120+23-6 = -3r + 137
8 + 7 = 15, so 6 + 9 = 15
Answer:
(6x6x6x6)x(6x6)
Step-by-step explanation:
6 to the power of 4 times 6 to the power of 2
If a number a is to the power of b, that means a multiplied by itself, b times
eg 4 to the power of 3 means 4x4x4
hence, 6 to the power of 4 (or superscript four) means 6 itself, 4 times
so, 6x6x6x6 multiplied by 6x6
