Answer:
56 quizzes
Step-by-step explanation:
40 quizzes = 5 weeks
To find the unit rate of quizzes / week, we can divide both sides by 5
40/5 quizzes = 5/5 weeks
8 quizzes = 1 week
Multiply both sides by 7 to find the amount of quizzes in 7 weeks
8 * 7 quizzes = 1 * 7 weeks
56 quizzes = 7 weeks

Answer:
800 calories
Step-by-step explanation
Jace wants his total to be: 1,900
He consumed: 1,500
He burned: 400
How much is left: ?
Your equation would look like: 1900=1500-400+x
First step is to add like terms so: 1500-400= 1100
Now you subtract the calories Jace has gained with the total he wants to achieve: 1900-1100= 800
The amount he needs to gain is: x=800
1,100 is not aa viable solution because he want to keep his calory intake at 1,900, and 1,100 is the total for the calories he already consumed and burned while at the gym.
Hope this made sense!
