Answer:
150 boys
Step-by-step explanation:
equation:
⇒ 5x + 4x = 270
add like terms:
⇒ 9x = 270
divide 9 on both sides:
⇒ [tex]\frac{9x}{9} = \frac{270}{9}[/tex]
solve:
⇒ x = 30
take original equation and subtitute 30 for x;
⇒5 x 30 + 4 x 30 = 270
⇒ 150 + 120 = 270
We can see that if there were 270 students, 150 would be boys and 120 would be girls.

I need to solve for x btw these are corresponding angles
Answers
Step-by-step explanation:
As we know corresponding angles are equal so
6x - 100° = 2x + 4° < being corresponding angles>
6x - 2x = 100 ° + 4°
4x = 104°
x = 104° / 4
x = 26°

b.) s=0.7p
c.) p=0.35

Answers
Answer:
0.70p

Answer:
[tex]\sqrt{149}[/tex]
Step-by-step explanation:
The third side of a triangle can be any value in the range of -
1 ≤ a < 17.
What is a triangle?A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry.In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique planeGiven are two sides of a triangle as b = 7m and c = 10m.
The sum of two sides of a triangle is always greater than the third side. Mathematically -
a < {b + c}
a < {7 + 10}
a < 17
a ∈ [1, 16]
Therefore, the third side of a triangle can be any value in the range of -
1 ≤ a < 17.
