Step-by-step explanation:
Let F represent fruitshake and C chocolate milkshake
one fruitshake cost more 2R more than chocolate shake and
3F + 5C = R78,00
Then (78 - 6) ÷ 8 = 9
a fruitshake costs R11,00 and chocolate milkshake costs 9R,00
Answer:
-5 + 3(7.2 - 3.2) equals 7.
Step-by-step explanation:
The order of operations states the order in which different mathematical operations should be done first, you can use the mnemonic PEMDAS to remember the order to complete each operation. PEMDAS states that the order must be followed as Parenthesis, Exponents, Multiplication/Division, and Addition/Subtraction. In the expression -5 + 3(7.2 - 3.2), the three mathematical operations being used are subtraction, multiplication, and parenthesis, so based on PEMDAS, the order to complete them is parenthesis, multiplication, and subtraction. -5 + 3(7.2 - 3.2) = -5 + 3(4) = -5 + 12 = 7, so that is your final answer.
Answer:
"Equations can be multiplied by a constant to allow for elimination by addition or subtraction. This process is called Elimination by Multiplication. We multiply the first equation by "2" to prepare it for elimination by subtraction. Now that we know "x", we can use this information to solve for "y"."
Answer:
16, 32
Step-by-step explanation:
We need to solve for t in this compound inequality. Let's do that!
11 < 7 + 0.25t ≤ 15
4 < 0.25t ≤ 8
16 < t ≤ 32
Therefore, we know that it will take Clara more than 16 weeks and up to and including 32 weeks to grow out her hair.
Answer: 5x+4+2
Step-by-step explanation:
5x-1(-4+2)
