Can you try typing the problem instead of using voice to text. sorry I could not understand
D is the answerr to the first one.
Answer:
1. 5 + y = 7
⇒ y = 7 - 5
⇒<u>y = 5</u>
2. 3.8 = a + 2.5
⇒ a = 2.5 - 3.8
⇒ <u>a = -1.3</u>
3. 5 + p = 9 1/3
⇒ p = 9 1/3 - 5
⇒ p = 28/3 - 5
⇒ p = 28/3 - 15/3
⇒ p = 13/3
⇒<u> </u><u>p = 4 1/3</u>
Answer:
a = 5
Step-by-step explanation:
Since the triangle is right use the sine ratio to solve for a and
sin30° = , thus
sin30° = = , hence
= ( cross- multiply )
2a = 10 ( divide both sides by 2 )
a = 5
Answer:
x = 3 feet
Step-by-step explanation:
Perimeter of a rectangle = 2 x ( length + width)
Perimeter = 6x + 14
length = 3x
width = 2x + 1
Substitute the dimensions in the equation for the perimeter of a rectangle
2 (3x + 2x + 1) = 6x + 14
Divide both sides of the equation by 2
3x + 2x + 1 = 3x + 7
5x + 1 = 3x + 7
Collect like terms
2x = 6
divide both sides by 2
x = 3
