Toby rides his bike to school every day and to his best friend's house regularly. One week, he rode to and from school 5 times and to and from his best friend's house 3 times. He rode a total of 14.4 miles that week. The next week, he rode to and from school 4 times and to and from his best friend's house 6 times. He rode a total of 14.4 miles that week, too. This system of equations can be used to represent the situation:
5x+3y=14.4
4x+6y=14.4

whats the question though

Step-by-step explanation:

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90
