Using a system of equations, it is found that the equation that could be used to find the value of b is given by:
3×4−8=b
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
Fatima has 3 packs of batteries. Each pack contains 4 batteries, hence:
b = 3 x 4
She gives her brother 8 batteries to put in his toy robot, hence:
b = 3 x 4 - 8
Which means that the first expression is correct.

A computer and printer cost a total of $1101. The cost of the computer is two times the cost of the printer. Find the cost of each item.
Cost of computer:
Cost of printer:
Answer:
Cost of Computer: $734
Cost of Printer: $367
Step-by-step explanation:
These two equations can represent the costs; x = price of computer; y = price of printer.
x + y = 1101
2y = x
If you graph these, you get an intersection point of (734, 367). This means that the only place that both equations are fulfilled is on (734, 367).
Then you can check your work:
734+367=1101
367*2=734
Which rectangles have the same areas but greater perimeters than the one shown below? Choose all that apply.
A rectangle is shown with a length and height of 6 ft.
A.
12 feet long and 3 feet wide
B.
9 feet long and 4 feet wide
C.
8 feet long and 3 feet wide
D.
7 feet long and 4 feet wide
E.
18 feet long and 2 feet wide
The rectangles have the same areas but greater perimeters are 12 ft by 3 ft, 9 ft by 4 ft and 18 ft by 2 ft.
What is area?Area is the amount of space occupied by a two dimensional shape or object.
A rectangle is shown with a length and height of 6 ft. Hence:
Area = (6 * 6) = 36 ft²
Perimeter = 2(6 + 6) = 24 ft
For 12 ft by 3 ft:
Area = (12 * 3) = 36 ft²
Perimeter = 2(12 + 3) = 30 ft
For 9 ft by 4 ft:
Area = (9 * 4) = 36 ft²
Perimeter = 2(9 + 4) = 26 ft
For 8 ft by 3 ft:
Area = (8 * 3) = 24 ft²
Perimeter = 2(8 + 3) = 24 ft
For 7 ft by 4 ft:
Area = (7 * 4) = 28 ft²
Perimeter = 2(7 + 4) = 26 ft
For 18 ft by 2 ft:
Area = (18 * 2) = 36 ft²
Perimeter = 2(18 + 2) = 40 ft
The rectangles have the same areas but greater perimeters are 12 ft by 3 ft, 9 ft by 4 ft and 18 ft by 2 ft.

Solution :-
This triangle is a right angled triangle as we can see ∠POC, has a right angled sign. Now, we will assume the missing angle to be x, thus,
25° + 90° + x = 180° ( Angle sum property of a triangle )
115° + x = 180°
x = 180° - 115°
x = 65°
Thus, the measure of missing angle is 65°.
