Answer:
b is the correct answer ok
Each triangle thingy is 12.5 because the base of the triangle is 5 and the height is also 5 which equals 25 and thennn you divide it by 2 since it’s a triangle, duh. and then since there are 4 triangles you multiply them 12.5 by 4 which is 50. and the square in the middle is base:5 base:5 which equals 25 and if you add 25 and 50 together you get
answer: 75
A.) Let x be the number of swimming lessons she had, then
402 - 15x = 237
b.) 15x = 402 - 237 = 165
x = 165/15 = 11
She had 11 swimming lessons
c.) Let the number of lesson she had be y, then 19y = 237
y = 237/19 = 12 lessons
She can pay for 12 lessons with her remaining $237.
The slope-intercept is the first option, y=-3x-6
