Answer:
Step-by-step explanation:
The marked angles form a linear pair, so have a sum of 180°.
(4a +10) +(6a) = 180
10a = 170 . . . . . . . . . . subtract 10
a = 17 . . . . . . . . . . . . . divide by 10
__
Then the measure of angle ABC is ...
∠ABC = 4a +10 = 4(17) +10 = 68 +10 . . . . . substitute 17 for 'a'
∠ABC = 78°
Answer:
It is already solved!
Step-by-step explanation:
It is meant to be in y = mx + b form where x is the slope and b is is the y-intercept.
Answer:
y = mx + b is the slope intercept form of writing the equation of a straight line
Step-by-step explanation:
y = mx + b is the slope intercept form of writing the equation of a straight line. In the equation 'y = mx + b', 'b' is the point, where the line intersects the 'y axis' and 'm' denotes the slope of the line. The slope or gradient of a line describes how steep a line is.
Step-by-step explanation:
Number of children not allergic to peanuts = 40 - 14 = 26.
Percentage = (26/40) * 100% = 65%.
