Answer:
330 square inches
Step-by-step explanation:
99 x 5 =495
495 x 2/3 =330
Answer:
x= 7
Step-by-step explanation:
1st step: Multiply the factor (outside number) with the numbers and variable(s) in the box. This results in 2(x-3) = 2x-6
2nd Step: continue the rest of the equation since there are no more brackets left so 2x-6-12=-4
3rd Step: send -12 to the other side of the equation (side changes sign changes) so it will become 2x-6=-4+12 (You are actually supposed to make the variable alone on one side of the equation so that you would be able to calculate its value)
4th step: 2x-6=8 ---> send -6 to the other side as well which will then result in 2x=14
5th step: since 2 is being multiplied by x, when you send it to the other side (to make x alone) you will divide 14 by 2 ( sign of 2 changes from multiplication to division)
Final Step: x=7
Answer:
it would cost r1.4
Step-by-step explanation:
because if you divide 70 by 50 to get to 1 muffin it. out 1.4 r
Answer:
you have to write it down on a piece of paper and go from there
Step-by-step explanation:
Step-by-step explanation:
3x + 4 + 2x +7
= 3x + 2x + 4 + 7
= 5x + 11
