Answer:
x+7=90 find the value of x
Step-by-step explanation:
Answer:
5 (1+1)=5 (2)=10
Step-by-step explanation:
you just substitute both X and Y with 1 and calculate it
Answer:
so you would use y=mx+b right? so if you would use this you would need to plug in x and the y-intercept so...
Step-by-step explanation:
x=1/.5
y= is the y-intercept!
Answer:
680
Step-by-step explanation:
Ratio of red to white 4 : 7
Number of white = 280
White + red buttons = x
7x / 11 = 280
7x = 280 * 11
7x = 3080
x = 3080 / 7
x = 440
Number of red buttons 440 - 280 = 160
Number of red bottons ;
Blue + red buttons = x
3 : 2 ; blue : red
3 + 2 = 5 ;
2x / 5 = 160
2x = 160 * 5
2x = 800
x = 800 / 2
x = 400
Number of Blue buttons :
400 - 160 = 240
Total :
White + red + blue
280 + 160 + 240 = 680 buttons
I'm assuming it would be the same shape? That's also assuming that it's referring to congruent shapes and angles.
