Find the value: 3 7r +5 8s r=14 s=8

Plug in values: First, plug in the values of r and s into the expression: 3(7r) + 5(8s).Calculate 7r and 8s: Now calculate the value of 7r and 8s: 7(14) and 8(8).Multiply by coefficients: 7 times 14 is 98, and 8 times 8 is 64.Calculate final value: Next, multiply these by their coefficients: 3(98) + 5(64).Add values together: 3 times 98 is 294, and 5 times 64 is 320.Get final sum: Finally, add 294 and 320 together to get the final value.The sum of 294 and 320 is 614.

Q. Find the value:

3 \times 7r + 5 \times 8s \quad r=14 \quad s=8

Plug in values: First, plug in the values of $r$ and $s$ into the expression: $3(7r) + 5(8s)$ .
Calculate $7r$ and $8s$ : Now calculate the value of $7r$ and $8s$ : $7(14)$ and $8(8)$ .
Multiply by coefficients: $7$ times $14$ is $98$ , and $8$ times $8$ is $64$ .
Calculate final value: Next, multiply these by their coefficients: $3(98) + 5(64)$ .
Add values together: $3 \times 98$ is $294$ , and $5 \times 64$ is $320$ .
Get final sum: Finally, add $294$ and $320$ together to get the final value.
Get final sum: Finally, add $294$ and $320$ together to get the final value.The sum of $294$ and $320$ is $614$ .
