Answer:
an ostrich can run 45 miles half an hour
Answer:
175 cm
Step-by-step explanation:
assuming it's a right triangle, the formula used is A= (1/2)(base)(height)
so (1/2)(14)(25)
which equals 175
Two times a number plus seven

i think four of them has created an expression that was equivalemt to the original.
Answer:
The equation y = 20x is proportional ⇒ B
Step-by-step explanation:
- The proportional relationship is represented graphically by a line passes through the origin point
- The equation of the proportional relationship is y = m x
Let us solve the question
<em>Substitute </em><em>x by 0</em><em> to find the value of y, if </em><em>y = 0</em><em>, then the line represents this equation </em><em>passes through the origin point,</em><em> then the equation shows a </em><em>proportional relationship</em>
∵ y = 50x + 2
∵ x = 0
∴ y = 50(0) + 2
∴ y = 2
→ That means the line that represents the equation does not pass through
the origin point
∴ The equation y = 50x + 2 is not proportional
∵ y = 20x
∵ x = 0
∴ y = 20(0)
∴ y = 0
→ That means the line that represents the equation passes through
the origin point
∴ The equation y = 20x is proportional
