Sagot :
Answer:
[tex]\huge\boxed{\boxed{\bf\:4r + 11}}[/tex]
Step-by-step explanation:
Given,
- C = r + 7
- D = - 2r + 3
We need to find the value of 2C - D. To solve this, we need to substitute the values of C & D in the expression. So,
[tex]\tt\:2\:C - D\\\\\sf\:{Substitute \: the \: given \: values}\\\\\tt\:= 2(r + 7) - (-2r + 3)\\\\\sf\:Now, \: follow \: the \: distributive \:property\\\\\tt\:= 2r + 14 + 2r - 3\\\\\sf\:Rearrange\:the\:terms\\\\\tt\:= 2r + 2r + 14 - 3\\\\\sf\:Do \: the \: required \:arithmetic \: operations\\\\=\boxed{ \bf\:4r + 11}[/tex]
[tex]\rule{200}{2}[/tex]
- The answer will be 4r + 11 in the standard form.
[tex]\rule{200}{2}[/tex]
Hope this helps!
The expression that equals 2C - D is 4r+ 11
How to determine the expression
The expressions are given as:
C=r+7 and D=-2r+3
The expression 2C - D is calculated as follows:
2C - D = 2 * (r + 7) - (-2r + 3)
Expand
2C - D = 2r + 14 +2r - 3
Collect like terms
2C - D = 2r +2r+ 14 - 3
Evaluate the like terms
2C - D = 4r+ 11
Hence, the expression that equals 2C - D is 4r+ 11
