If jack drives 876 miles to Mexico Tuesday, and 986 miles wens day , what-is the total miles he drove?
Answers
The distance travelled by Jack to Mexico on Tuesday is 876 miles.
The distance travelled by Jack to Mexico on Wednesday is 986 miles.
To determine the total miles he drove ,
The sum of the distance travelled by Jack to Mexico on Tuesday and Wednesday.
Let the total miles drove is denoted as T.
[tex]T=876+986[/tex][tex]T=1862\text{ miles.}[/tex]Thus the total miles drove is 1862 miles.
The animals at a safari park include gorillas, buffalo and wallabies. There are 24 more buffalo than there are gorillas. There are 7 times as many wallabies as there are gorillas. There are the same number of buffalo as there are wallabies. How many gorillas are there at the safari park?
Answers
The number of gorillas at the safari park is 4.
Let the number of gorillas at the safari park be x.
It is given that there are 24 more buffalo than there are gorillas.
Number of buffalo at the safari park = 24 + x
There are 7 times as many wallabies as there are gorillas.
Number of wallabies at the safari park = 7x
Now, the number of buffalo is the same as the number of wallabies.
So, we equate their numbers to find the value of x i.e. number of gorillas.
24 + x = 7x
7x - x = 24
6x = 24
x = 4
Therefore, the number of gorillas at the safari park is 4.

June, Gavyn and Alex share some sweets in the ratio 3:5:4. June gets 39 sweets. How many sweets are there altogether?
Answers
Answer:
156
Step-by-step explanation:
This is a question in proportion and ratio
Since the ratio in which the sweets are shared is 3: 4 : 5 we can say that the proportion of total sweets that June gets is 3/(3 + 4 + 5) = 3/12 = 1/4
Let the total number of sweets be S
Then 1/4th of this will be June's share and we are given that the actual number June gets is 30
So we have 1/4 x S = 39
Multiplying both sides by 4:
4 x 1/4 x S = 39 x 4
S = 156
So there were 156 sweets altogether

$15 per hour is the basic rate at a factory. After a 48-hour basic work week, overtime is paid time and a half.
(a) If no one worked overtime and the factory paid $15 840 in wages one week, how many workers are in the factory?
(b) During another week, a worker in the factory earns $810 in wages for himself. How many hours did he work for?
Answers
Answer:
(a) There are 22 workers are available in the factory.
Step-by-step explanation:
(a) Let the number of workers in the factory be x.
Basic rate = $15
Working hours in a week = 48 hours
Total wages in a week = $ 15840
If no overtime is to be paid then according to question,
Amount paid to 1 worker = 48 X 15 = $ 720
Amount paid to x worker = 720x
15840 = 720
x = 15840/720
x = 22
Help ASAP solve for the value of Z

Step-by-step explanation:
The angle in the middle is a right angle with a measure of 90°
Together, all three angles, makes a stright angle which is measured 180°.
So we can write the following equation to find the value of z:
5z + 1 + 59 = 90 (we don'thave to include the middle angle since we already its measure)
add like terms
5z + 60 = 90 subtract 60 from both sides
5z = 30 divide both sides by 5
z = 6

The graph of the linear equation y = 20 + 10x for the given scenario is attached below.
The Cartesian coordinates of a specific point on the Euclidean plane can be thought of as each solution inside the scenario involving two variables.
A linear equation's solutions define a line inside the Euclidean plane, and each line may be viewed as the aggregate of all solutions to a linear model with two variables. This is how this category of equations came to be known as "linear." The solutions to a system of equations with integer variables collectively constitute a hyperplane in the Euclidean space with size n. (a subdomain of dimension n₁).Because linear equations may frequently accurately represent non-linear systems, they are used extensively in all branches of mathematics as well as in physics and engineering.Here the equation is given as y = 20 + 10x
Therefore at x = 0 , y = 20 and at y = 0, x = -2
This represents that the fixed monthly fee is 20 and the daily fee is 10.

18) Before Santiago donated 84 of his books to the Goodwill store, he had twice as many books
as Alex. After the donation, Alex has twice as many books as Santiago. How many books
does Alex have?
Answers
Alex has 56 books.
Let the number of books Santiago has be x. So, after the donation, the number of books with Santiago is (x - 84). Let the number of books with Alex be y.
Before the donation -
x = 2y : equation 1
After the donation -
y = 2(x - 84) : equation 2
Keep the value of x from equation 1 in equation 2
y = 2(2y - 84)
Performing multiplication on Right Hand Side of the equation
y = 4y - 168
Rearranging the equation
4y - y = 168
Performing subtraction on Left Hand Side of the equation
3y = 168
y = 168 ÷ 3
Performing division on Right Hand Side of the equation
y = 56
Therefore, Alex has 56 books.
