Solve for x: 10(x + 1) = 2x - 7

Lisa [10]

Answer:Simplifying

x = -2.125

Step-by-step explanation:Add '-10' to each side of the equation.

10 + -10 + 8x = -7 + -10

Combine like terms: 10 + -10 = 0

0 + 8x = -7 + -10

8x = -7 + -10

Combine like terms: -7 + -10 = -17

8x = -17

Divide each side by '8'.

x = -2.125

Simplifying

x = -2.125

Dana saved 450 for food for her upcoming vacation. The breakfast was included with their hotel, but lunch and dinner are not. Wh

zzz [600]

Answer:

$10d + 40r \leq 450$

Step-by-step explanation:

Given

$Savings = 450$

$Dana\ Cooks, d = 10$

$Restaurant, r = 40$

Required

Represent this as an inequality

When Dana cooks;

$Cost\ per\ meal = 10$

$Cost\ per\ d\ meals = d * 10$

$Cost\ per\ d\ meals = 10d$

At Restaurant

$Cost\ per\ meal = 40$

$Cost\ per\ r\ meals = 40 * r$

$Cost\ per\ r\ meals = 40 r$

Add these two results:

$Result = 10d + 40r$

<em>To represent as an inequality, the above result must be less than or equal to Dana's total savings</em>

i.e.

$10d + 40r \leq 450$
